Stuck orgasm

A guy went into a bar and met a nice girl. They have a few drinks and soon wound up at his place, in bed. They're having a great time. She was on top when suddenly she had an epileptic seizure -- she was shaking and foaming at the mouth. Our uninformed male thought this was incredible -- best sex he'd ever had. He finished, but she is still shaking and thrashing about with her seizure. He began to get nervous and took her to the emergency room. A nurse asked what the problem was and he replied, "I think her orgasm's stuck!"
