If you're aiming for shock, you got it.
If you're doing this to practice for better work. Good for you. If that's what's what you're aiming for...the sound was good... The joke went over my head though. The score was for shock factor, which lead to gross-out factor. If you were going for suprise, you got it, at least from me. Hope you come up with something "different" for your next one.
