Slippers And Friends

A man tells his son to go get his slippers from his daughter's room. When the son enters the room he sees two smoking hot girls in his sister's room.

"My dad told me to f*ck both of you" - says the son

The sister gets mad and proposes to ask the father if that's really the case. The boy agrees and shouts:

"Dad which one?"

"Both of them, you retard" - shouts back the father
