Johnny and Jim are camping in the desert.  Early in the morning, while Jim is still sleeping, a snake bites his prick!  "AAIIIIIII!!"

He panics, and John panics. "What can we do?"  After talking it over, they decide that Jim should stay where he is, and Johnny should go for help.

So Johnny starts off and soon encounters a town where he finds the local doctors office.  Johnny convinces the receptionist to let him quickly talk to the doctor.  "My friend is bitten by a snake.  What do we do?"

"What kind of snake was it?"

"It was about one meter long, sort of green and yellow."

"Whoa boy.  Those are very dangerous!"

"What can we do?"

"The only thing you can do is suck the poison out.  Otherwise your friend will die!"

So Johnny goes back to his friend and starts packing up his gear.

Jim says,  "Well, what did the doctor say?"

Johnny says, "You're going to die."
