A little boy walks into his parent's room to find his father railing his mom pretty good. The little boy stands confused then runs out. The Dad later decides to have "the talk" with the boy.
"Dad, what was between mommy's legs?" The boy asks
"Son, that's called a pussy"

About two weeks later, the boy walks in on his father watching porn. The boy stands there for a minute, confused again. The dad sees the boy and quickly turns it off.
"Dad, what's between that woman's legs?" The boy asks.
The dad is confused and responds
"Son, remember? I said its called a pussy... just like mommy."

"But dad, that woman had a pretty flower between her legs, mommy had roast beef."
