I remember some funny ones:
Not now sweety (daughter) I'm recording a Starcraft replay.
but dad, Spot (dog) just peed on the carpet... and I think he's going to do the other thing.
... replay pauses...
you hear the guy in the background muttering and sending the dog outside.

Hatamaki made some good ones. I liked his IntotheRainbow vs. Nada one with his sidekick/roommate Epsilon.
"Hi, this is Epsilon. I'm going to help Hautamaki by reading these questions he wrote for me to ask. j/k.
Long live RWA!
