Start out with two girls getting hot and heavy on a bed, dressed as the Twin Towers. All of a sudden BOOM! Guy dressed in an airplane outfit throws open the door. Twin Towers girls are confused. The dude starts going to pound town behind one of the Tower girls while she eats out the other Tower. Oh wait! Another guy dressed as an airplane comes through the wall Kool-Aid Man style and starts getting it on with the other Tower.
(Just thought this was funny)
