A family of Michigan football fans head out one Saturday to do their Christmas shopping. While in the sports shop the son picks up an Michigan State jersey and says to his older sister, "I've decided to become a Spartan fan and I would like this for Christmas".
His big sister is outraged by this and promptly whacks him round the head and says, "Go talk to mother".
Off goes the little lad with the Michigan State jersey in hand and finds his mother. "Mom?"
"I've decided I'm going to be a Spartan fan and I would like this jersey for Christmas".
The mother is outraged at this, promptly whacks him around the head and says, "Go talk to your father!"
Off he goes with the Michigan State Jersey in hand and finds his father.
"I've decided I'm going to be an Michigan State fan and I would like this jersey for Christmas".
The father is outraged and promptly whacks his son around the head and says, "No son of mine is ever going to be seen in THAT!"
About half an hour later they're all back in the car and heading towards home. The father turns to his son and says "Son, I hope you've learned something today?"
The son says, "Yes, Dad, I have."
"Good son, what is it?"
The son replies, "I've only been a Spartan fan for an hour and I already hate you Michigan ba*tards."
