yo momma's so fat, she ate james's giant peach for breakfast!
yo momma's so fat, she needs mapquest to find her own neck!
yo momma's so fat, she has more chins than a hong kong phone book!
yo momma's so fat, I tried to drive around her, but I ran out of gas!
yo momma's so fat, she sits next to everybody!
yo momma's so stupid, somebody said it was chilly outside, so she ran outside with a spoon!
Enjoy! I made up a few of those when I was bored. I'm off to bed...
