Haha, great thread, and that's like my 2nd favourite episode quote of all time! My favourite being:
"I'm Not A Miner! No, You're An Idiot!" - brought to you by Tara & Wil from TAR2!
Other great ones:
"This Is More Important Than Your Pants Falling Down" - Ian from TAR3
"I'm Going To Jail" - Colin from TAR5 (not that funny, but the concept of him going to jail was quite funny)
"Houston, We Have An Elephant!" - Uchenna from TAR7
"Paolo Family, You Look Ridiculous!" - PHIL from TAR8
"We Are Trying To Make Love, Not War" and "I'm Sorry I'm Wearing A Bathing Suit, It Is Very Weird, I Know" - Mirna from TAR11.
"Cherry On Top Of THe Sundae That's Already Melted" - Nathan from TAR12
"They Thought Godzilla Was Walking Down The Street" - Flight Time from TAR15
"Ali Baba In A Suit" - Nick from TAR17
Loads more to mention, but I thought I'd start off with these!
