Funny Comeback

Roses are red
Violets are blue
Your ass looks fine and so do you
I took you to my place
And everything was fine
Then I said, "I'll be the six if you be the nine."
So it started out nice
We ended up in bed
Everything got hard so I showed her my head
So we were under the blankets
It was hot so I was about to smuther
I lifted up the blanket and found out it was your mother.
