I don't know if it counts as a one liner but when Tobias is talking bout Robert Redford.
"But give me an old pro like Robert Redford anyday, ohhh I would lay in bed with that man all day, And I wouldn't just lie there Michael Bluth if that's what you're thinking."
Lol Yeah basically anything Tobias said especially when he was listening to himself on the tape recorder.
"Even if it means me taking a chubby I will suck it up."
" I've made a huge mistake"
Best one liner from the whole Bluth family, well, most of them at least say it, Gob the most.
Well a lot of the great one liners come from Gob and Tobias but since Gob is my favourite character, I'll list a few of his:
While searching for hermano: "Thanks mon frere - that means brother in french. I don't know how I know that, I took 3 years of spanish"
""Portugal? So, flying down South America way, are you Mikey?"
"There's not a lot of logic to it. It's kind of like on a boat with "Women and children first."
"I'm a failure. I can't even fake the death of a stripper"
"Gilligan killed the skipper-stripper!"
Mines not really a one liner but one of the funniest AD moments for me was in "the One where Michale Leaves (2) when Michael says to George Michael "Are you too old to sit on your dads lap and drive"? and George Michael says "Yeah, I think I am" but in the next scene after they have been stopped by the cops George Michale is sitting on Michaels lap. I loved it! looked so fricken hilarious!!!
