I heard this comedian on the radio yesterday. His name is Aaron Aryanpur and had this hilarious bit about needing a wife who was ready for SHTF.
He performs in Texas mostly, but is an up and comer on the national comedy scene, and I think we'll be hearing some good , funny stuff from him for a long time to come. You can also check him out at his website here.
I don't know about all of his stuff, but this bit is clean and family friendly. Check him out, and if you like his stuff on YouTube, leave him a comment and let him know you heard about him here at If It Hits The Fan.
