not sure if everyone will like it or not but..

little jonnys mom was gettin nailed by her bf when he walks in,
jonny sees her bf look at him and give him a wink as he closes the door,
a little while later the bf goes to check on him and as he opens the door he sees jonnys "gma" bent over in front of jonny,
wtf are you doing and jonny replies
"not so funny when its your mother is it!"
