For the Lulz - Thank Goodness

A girl comes home with her boyfriend and tells her mom they're going upstairs to her room. Then later her mom hears " baby baby baby ohhhhh baby baby baby ohhhhh " coming from the room. So her mom walks in and asks what they're doing. The girl shouts, "Mom! Get out! We're having sex" So her mom says, "Oh, thank goodness, I thought you were listening to Justin Bieber."
