Suck The Poison Out

2 friends were camping out one night, when all of the sudden one of them jumps up screaming,
“A SNAKE JUST BIT ME ON THE TIP OF MY PENIS!!”.
The other friend said, “don’t worry, I am going to town to find a doctor, I will be right back!”.
So he goes to town, and finally finds a doctor.
“Doctor!! My friend just got bit by a snake!!!” the friend says.
“It’s ok”, the doctor says, “all you have to do is suck the poison out.”.
The friend says thank you, and runs back to the camp site. The injured friends asks, “WHAT DID THE DOCTOR SAY? WHAT DID HE SAY?”
the other friend replies, “doctor said you gonna die!”
