Inside, was an unattractive, overweight woman, sitting on her sleeping bag, smoking a cigarette and drinking a beer.

The man, concerned he was soaking wet and likely to catch a cold, peeked into the open tent-flap.

"Excuse me ma'am, it's raining out here, mind if I come in to get out of the rain for a little while?"

"Sure," the woman replied, "On one condition. No funny business."

The man agreed and entered the tent.

He sat down on the sleeping bag next to her.

A few minutes later, the woman let out a loud fart.

"1:0," she said.

Five minutes went by, she ripped off another one, "2:0."

The man was curious.

"Ma'am, why are you farting then giving out the score?"

The woman responded, "I'm a bit bored, there's not much to do, so I thought I'd start a farting competition."

"Sounds like you're winning," said the man. He decided to beat her at her own game, and let out a massively loud fart which shook the tent.

"2:1," he said, ripping off another one, "2:2."

She looked at him, somewhat impressed, "You're fucking good at this!"

Determined to win, she ripped off another fart, only this time she ended up shitting the sleeping bag.

She blew a whistle, and said, "Half-time, change sides."
