can you think of any? I can. On ALL IN THE FAMILY once Jean Stapelton played-besides her regular role of Edith-a woman who looked exactly like her. On McHALES NAVY once, in the final season when it was set in Italy, Ernest Borgnine, who played Lt. Commander Quinton McHale, also played his look-alike Italian cousin. On MY 3 SONS, Fred McMURRAY also played Steve Douglases look-alike scottish cousin. Lisa Kudrow played a waitress named Eserla on MAD ABOUT YOU and when FRIENDS started, they made her Phobes twin sister. She continued to play Ersela on MAD ABOUT YOU and when that ended she also played her on FRIENDS a few times. Max Baer also played Jethros twin sister Jethrine on the first season of THE BEVERLY HILLBILLIES. He gave up playing Jetherine when the makeup started to affect his skin.
And, of course Patty Duke played look-alike cousins Patty & Cathy Lane on THE PATTY DUKE SHOW.

Andy Kaufman played both Latka Gravas and Vic Ferrari on Taxi.

On Bewitched Elizabeth Montgomery played both Samantha & Serena.

On I Dream of Jeanne Barbra Eden played her sister and Jeanne.

what's wrong with me?:lol: Those 2 are the most OBVIUS ones and I forgot them!

and here's another one that I just remembered: once on THE HONEYMOONERS, Jackie Gleason played Ralph and a gangster who looked like him. But I don't know if that counts since it was one of the THE HONEYMOONERS sketches he did, which are called "the lost episodes".

oh, and I just thought of another one-twice on THE ODD COUPLE Tony Randall also played Felixes father, once he also played his grandfather, and once Jack Klugman also played Oscars father.

How could you forget Morticia and Ophelia (Carolyn Jones) on The Addams Family?

Ted Cassidy playing both Lurch and Thing on The Addams Family? (OK, the latter role was just his hand, but that should count for something, huh? :lol: )

On The Brady Bunch, both Florence Henderson and Robert Reed played the grandparents, Ann B. Nelson played Alice and Emma (I think) and Chris Knight played Peter and his lookalike classmate.

Over at Little House, the Greenbush twins played side by side in one episode as Carrie and her imaginary friend. Years later the Olsen twins did the same on an episode of Full House.

I forgot about THE ADDAMS FAMILY and THE BRADY BUNCH and I didn't know about LITTLE HOUSE ON THE PRARIE and FULL HOUSE.

Larry Storch played Cpl. Agarn in "F Troop." In a second season episode, he also played his cousin Lucky Pierre. Or as they described him "He looks like Agarn with a beard." I believe he also played another cousin in the first season, but I have yet to watch that episode.

On "The Monkees" there was an episode where Micky played a cousin of his, who was named Baby Face. he was a criminal. And there was one where Davy had a Prince who looked just like him (obviously because Davy Jones played both roles).

On "The Munsters", Fred Gwynne played his brother Charlie as well as, of course, the classic Herman Munster.

And just for the record, I hate when they do that, lol.

Bea Arthur once played Dorothy's grandmother in a flashback on The Golden Girls.

On "Martin" he played...
Shanana (however you spell her name)
Mother Payne
Otis
Roscoe
Jerome
The Security Guard (I can't think of his name)

My son thought of this one; Jaleel White played Steve Urkel and Stefan on
Family Matters.

Roseanne: Michael Fishman played a young Roseanne in a flashback
Full House: John Stamos played a visiting cousin from Greece
Bosom Buddies: Tom Hanks and Peter Scolari played Buffy & Hildegard
The Amanda Show: Doesn't she play many characters?
(King of the Hill: Hank played his half brother from Japan)
(The Flintstones: Fred becomes obnoxious "Frederick" after he is hit on the head)

My son thought of this one; Jaleel White played Steve Urkel and Stefan on
Family Matters.

Also remember that he played a handful of other characters, some with the last name of Urkel as well. Here's what I can think of right now:

Myrtle Urkel
Bruce Lee Urkel
OGD
This may not count, but he did the voice of "RoboNerd" the robot he created.

Additionally, on Family Matters, Reginald VelJohnson (Carl) also played Big Daddy Urkel on a few episodes.

And Jo Marie Payton played a mission control woman on the finale, after she gave up the role of Harriette.

Here are the classic Charles In Charge characters playing different roles...

Charles as Chazz after he hits his head in the two part episode and All That Chazz.
Buddy as Buddy's cousin in Lost Resort.
Jamie as a cousin from Arizona.
Lillian playing two sisters like the rich eccentric aunt of Charles and the wise-cracking aunt who works at a carwash business.

:lol:

-On an episode of Who's the boss? Tony Danza played both Tony Micilli and a guy who Angela met on a vacition who was supposed to be the opposite of Tony.

-There was a black & white episode on who's the boss? where Tony Danza and Judith Light played different roles.

On Threes Company didn't John Ritter play his own cousin or brother named Austin? I think he may have worn a cowboy hat and talked with a Texas accent.

:lol: Oh yeah that was a funny episode

He played Austin

Soleil Moon Frye played Punky Brewster and also played a Native American named Moon-something.

On an episode of Amen, Anna Maria Horsford played both Thelma and her late mother in a flashback episode.

Jasmine Guy played of course Whitley and Whitley's cousin on an episode of A Different World.

David Lander played Squiggy and Squiggy's sister, Squindolyn on an episode of Laverne & Shirley after they moved to California. And poor Carmine had to take her own a date.

On Mork & Mindy, Robin Williams played himself in one episode. Redd Foxx appeared as himself in the "Fred Meets Redd" eppie in the last season of [I]Sanford and Son.
