"Well, ain't this place a geographical oddity. Two weeks from everywhere!" from O Brother, Where Art Thou?
I love that one! Also, do you remember...
"We - thought - you - wes - a - TOAD"
"Well, ain't this place a geographical oddity. Two weeks from everywhere!"
Just about any line whatsoever from "O, Brother" had me p**ing myself -- how about :
"I'm a Dapper Dan man!"
"Yer losing some o' yer foldin' money!"
"Aw, not the livestock!"
"Do not seek the treasure!"
"You insulted mah kin!"
"He's a keeper -- he's bona fide!"
"That ain't mah ring! That's Aunt Lurleen's ring!"
and my all-time favorite, from Pappy O'Dan'el:
"It's a good thing your ma died givin' birth to ya, 'cause if she could see ya now, she'd die all over again!"
