i my favorite is when tobias gives buster his "analrapist" card. buster yelps when he sees the card, and tobias explains how "analrapist" is really pronounced. then buster goes "it's not the pronounciation that bothered me."
haha such a good show. too bad fox rejected them

My favorite is when Tobias is part of Blue Man Group and comes downstairs covered in blue and says to Michael "I just blue myself" and Michael replies with "There's got to be a better way to say that." Classic!

May I add the quote:

“I’m afraid I blew my wad on what was supposed to be a dry run and now I’ve got a bit of a miss on my hands.”

After being turned down by Bob Loblaw because he is working on his Law Blog, Tobias responds:

"Bob Loblaw's Law Blog. You sir, are a mouthful!"

"Banger in the mouth?"

T - "oh thats right, In american you call it a sausage in the mouth"
Michael- "actually we just call it a sausage"

one of my favs

I will suck up a chubby if I have to

There are so many... maybe when he says:

Well, let's just say that I'm buy-curious.

Or of course:

Michael, you are quite the cupid. You can stick an arrow in my buttocks any time.

Either when George Michael says he isn't scared of sex and Tobias is like " Oh, good. Have sex with this girl right now. Do it, go. Get in there. Have some sex with her right now. I didn’t think so.”
or
"I'd like to kiss that man between the cheeks, so to speak"
or
"C'mon don't leave your uncle T-bag hanging"

Tobias has the best lines- how about:

"Excuse me, do these effectively hide my thunder?"
or
"Well excuse me for liking the way they frame my junk!"
both in reference to his thongs.
