A man walks into walks in to a sperm bank wearing a ski mask and holding a gun. He goes up to the nurse and demands that she open the door on the sperm bank vault. The nurse replies, "But sir, it's just a sperm ban."
The man yells, " I DON'T CARE JUST OPEN IT NOW!" The nurse opens the door and stands aside. The man then says to the nurse, "Take that sample and drink it." She looks at him, "But they're sperm samples" "DO IT!", he replies.
So the nurse sucks it back. "That one there, drink it as well", he said. Finally after 5 samples the man rips off his ski mask turns to his wife and says "See honey, it's not that hard"
