Bedroom game (adult humour)

A little old couple prepares to go to bed. They no sooner hit
the pillows when the old man farts and says, "One nil."
His wife rolls over and says, "What in the world was that?"
The old man replied, "It's fart football."
A few minutes later his wife lets one go and says, Goal - 1-1".
After about five minutes the old man lets another one go and
says,"Penalty- 2-1."
Not to be outdone, the wife rips out another one and says,
"Penalty - 2-2."
Five seconds go by and she lets out a little squeaker and
says,"Free Kick - Goal, 3-2."
Now the pressure is on the old man.
He refuses to get beaten by a woman so he strains real hard, but to no avail.
Realising a defeat is totally unacceptable he gives it everything he's got, and accidentally he craps in the bed.
The wife says, What the hell was that?"
The old man says, "Half time, change sides"
