There is a post-Richie ep of Happy Days where Howard and Marion are going to see a movie, The Music Man to be exact.

Marion says, "I just love that little red headed boy. He looks so much like Richie at that age." The camera then zooms on the picture of the little boy in the movie poster, who was of course, Ron Howard. Howard says, "Oh, you've got to be kidding, Marion", then they walk into the theater. LOVED it!! :lol:

Wasn't that cute???? I love that!

I can't think of any right now, but I know there are some.

On Bewitched Uncle Arthur was introduced during the black and white episode of the second season. He made Darrin believe he could put a hex on Endora by making him go through this embarrasing encantation. Yagazuzi, Yagazzi zim, and he'd blow a horn and wiggle his noze. In the 3rd season which switched to color Uncle Arthur visits again and teases Darrin about that fiasco, it was funny. Uncle Arthur said Hi or how is Yagazuzi, lol.

I Love Lucy it wasn't mentioned, but it is sort of implyed. During a scene Lucy is holding look magazine and the real life Desi Jr. was on the cover.

Roseanne-When Lecy was replaced by Sara Chalke they teased her about it, then when Lecy returned or alternated the role they asked her, where have you been. During the ending of an episode both Becky's appeared doing the opening theme of The Patty Duke Show. Becky #2 stated that the second Darrin on Bewitched was her favorite, lol.

Married With Children- When they added the kid to the cast, he didn't work out and disappeared from the show. Later his picture appeared on a milk carton as a missing child.

One of my favorites was from "Mad About You."

In the first season Paul (Paul Reiser) had a slacker budd named Selby, who disappeared after the first season without any mention.
Cousin Ira became Paul's new buddy.

A few seasons later, Jaime (Helen Hunt) mentions Selby in passing, to which Paul responds "Yeah, whatever happened to him?"

:lol:

Home Improvement

This episode was just on a few weeks ago. Tim is babysitting for their niece. Tim, Randy & the neice are playing with stuffed animals. There is a joke about the Lion King which is voiced by JTT and Buzz Lightyear which is voiced by Tim. Can't remember the exact wording, but I thought it was really funny.

Growing Pains

There was once a joke about Maggie looking like the swimmer Donna Deverona, who is Joanna Kerns sister in real life.

On the series finale of Becker, Ted Danson looks at a patient sheet for 'Mr Neilson', and says something like "there is nothing wrong with these numbers", refering to the ratings of the show.
