The WB cartoon falling object.
blowing nose on napkins (I can’t do that)
a bunch of girls giggling for no reason (I think)
a cocked shotgun (even if I’m for gun control)
the trumpet trill used in “Don’t Believe the Hype” and other rap songs.
A woman hitting high notes when getting it on
I’ll have to say that my favorite non-sexual sound is, like Snoopy’s the sound of anime swords. Only I’ll back it up a few seconds and say it’s the sound of the sword being drawn before the big fights. It’s the promise that all hell is going to break loose, and it’s just cool. 
My favorite sound of all time is the sound of lots of people walking on a hard surface with heels on–pumps, boots, stiletto heels, doesn’t matter.
I love the sound water makes, whether it be rain, waves, or a stream, I just love it.
