Writhing Jokes

Two friends, Al and Mike, were walking through the woods, when suddenly a snake jumped up and bit Mike on the penis. He was quickly down on the ground writhing in pain, so Al yelled,"Wait here while I run and get help!" So Al runs into town, gets to the doctors office, and tells him what happened. The doctor tells him he cannot leave the office, but told Al he would need to bite open the wound and suck out all of the venom. Al runs back into the woods, and finds Mike still writhing in pain.
"What did the doctor say?" asked Mike. And Al told him,
"The doctor says you're gonna die!"
