An old man and his wife have gone to bed. After lying in bed for a few minutes the old man cut a fart and says "seven points."
His wife rolls over and asks, "What in the world was that?"
The old man says, "Touchdown, I'm ahead 7 to nothing."
A few minutes later the wife lets one go and says, "Touchdown, tie, score."
After about ten minutes later the old man farts again and says, "Touchdown I'm ahead 14 to 7."
Now starting to get into this the wife quickly farts again and says, "Touchdown, tie score." The old man strains really hard but, to no avail he can't fart, so not to be outdone by his wife, he gives it everything he has and strains real hard to get out just one more.
Straining, the old man tries so hard he poops in the bed. The wife asks, "Now what in the world was that?"

The old man replies, "Half-time, switch sides."
