Scripts for a Humorous Duet Acting Scenes??

Me and a friend of mine are doing a Humorous Duet Acting scene for a speech competition next year, but we want to get a jump on it this summer! Does anyone know of anywebsites where I could find a script for free, for any AMAZING scripts that I could buy? Do you know any good authors of hilariously funny duet scenes?
Oh, I forgot to say, both characters must both be male, and the scene should be 8-10 minutes long.
Thanks!!
