When having sex at the top of a staircase, the man karate chops the woman between the shoulder blades, causing her to flinch and her arms flail backwards. He then proceeds to kick the woman's legs out from under her, grab onto her arms and ride her down the stairs.
"Dude, my girl told me she was pregnant"
"Damn! What are you going to do?"
"Shit man, I'm giving her the escalator tonight and aborting that fetus"
