I'm really sticking to just the episodes on DVD. That's why I'm only doing the first five seasons.

The 10 Best Episodes: (in order of appearance)
1. Sports and Leisure
2. Mother Wore Stripes
3. Murder, She Roast
4. This Old House
5. Das Plane
6. The Bank Dick
7. It's So Nice to Have a Mather Around the House
8. Another Wedding
9. The Faygitive
10. Boys Will Be Girls

The 10 Least Best - I won't say worst - Episodes: (in order of appearance)
1. Return to Nantucket (both parts)
2. Hell Hath No Fury Like a Policewoman Scorned
3. Love Means Never Having to Say Geronimo
4. My Brother's Keeper
5. The Bogey Men
6. Noses Off
7. Just Say No
8. Labor Pains
9. Say Uncle, Carlton (I can't stand Gilbert Gotfried!)
10. Exclusively Yours

This is, of course, my opinion. What are your choices?

Sadly, most of the first two seasons would clog my list.

My worst 10:

1. Stand up Kind of Guy (Jerry Stark, ugh).
2. Story of Joe (little too serious)
3. Girl from Nantucket (Mullalay's voice was annoying back then too)
4. Stew in a Stew (bitter Fay just isn't fun)
5. Around the World in 80 days (not much punch)
6. High Anxiety (the way that chick strong-armed Joe and Helen was annoying)
7. Terminal Christmas (only xmas ep I didn't like, the others always had a sense of comedic drama)
8. Always Room for Cello (Roy's endless acceptance of R.Gay, I mean J.!)
9. Plane Nine from Nantucket (aside from the light bulbs in the mouth, too serious)
10. The Late Mrs. Bigguns (too serious)

My best 10:

1. Joe Blows Parts 1 and 2 (tremendous energy)
2. It May Have Happened One Night ("I know when I've been licked..." LOL!)
3. Sleepless in Nantucket (Helen wrestling the water pistol from Brian)
4. Black Eye Affair (more tremendous energy!)
5. Long Distance Lament (Club Car chaos)
6. Date Package Number 7 ("This place looks different through my telescope.")
7. The Bank Dick ("Can't believe I'm getting robbed by a guy wearing two-toned wingtips!")
8. Two Jerks and a Jill (stuff at the gym was hilarious)
9. Blackout Biggins (great shame to Roy is always great)
10. A Decent Proposal (Joe gets Helen!)

I'll have to think about that. There are so many episodes I love that it's hard to narrow my list down to a couple of favorites.

I can list some of the episodes I really don't care for.

The Customer is Usually Right
The Gift, parts 1&2
Plane 9 from Nantucket
the Sandy Cooper episode
the first Carlton Blanchard episode

My list is rather small, didn't have many complaints:

Season 1-5, anything therafter.

I haven't seen every episode in the first five seasons, but I can list some of the ones so far in Season 1 and 2 that I don't like.
