Flight of the Conchords/Funny

Music

 * Almost all of their music is hilarious, but here are some specific examples:
 * "Hiphopopotamus vs. Rhymenoceros".
 * "Robots".
 * "Bowie", their tribute to David Bowie.
 * "Business Time", if you know what I mean.
 * Bret's music for The Muppets is full of meta hilarity.

Series
"Sinjay (threatingly): I'm going to count to 10! (awkward silence) Jermaine: Are you counting in your head? Sinjay: Yes. Jermaine: What number are you up to? Sinjay: Seven. (Jermaine and Bret run away)"
 * Most anything Dave says but especially: "It's not a fucking school play production. It's the bird." (Dave to the guys when trying to show them how to flip someone the bird).
 * Flight of the Conchords has a number of these, but this is one of the best:

"Murray: And one time... my whole platoon had to drink their own urine. Bret: Oh, were you lost? Murray: No, we were drunk. It was a party game. I didn't really like that part of the army. More tea, Jemaine?"
 * Murray telling the guys about when he was in the New Zealand army, while in fort they made in their bedroom.
