Definitely when Bender eats one fat free potato chip and a pile of bricks fall out his ass. Fry never comments on it.
Olestra was a fat-free “oil” manufacturers were using in potato chips, and there was a bunch of press about it causing diarrhea.
I love the follow up to this one of the times his ass plate is missing

20 SWEET
30 GOTO 10
I’m pretty sure this gag is from when Fry joins the police, but it always cracks me up.
The same episode he also mentions having a lot of paperless work to do. Not a background gag but a great line nonetheless.
Gotta be the gym scene where the woman is working out on the “Kegelcizer” and just squinting
Not a gag, but I really like how nibbler was set up right from the pilot.
I love the radiator woman from the radiator planet attending Fry’s funeral.
