I need some funny things to say in a rap?

There's this app on my android (They also have it for iphones) called AutoRap, and basically everything you say it turns into this crazy rap. Its hilarious. But I can't think of anything funny to say into it, so I need some help. Help me out and give me some weird/funny things to say in it.

Just ryme together words and make a story like
You better get out my face
Before I smack u with this shoe lace
I might catch a case
Cause I sprayed u with some mace
You got a fat face
You look like a mouse
Go eat some cheese
And tel your mama to get on her knees

2Chainz can help you then, he got some hilarious lyrics.

"SHE GOT A BIG BOOTY So I CALL HER "BIG BOOTY" "
