The most important Badger rule is: If you are losing, start badgering your opponent to distract him so you can win the game.
Now, I know you're thinking that sounds like poor sportsmanship, but it's all in good fun!
For example, if you are playing basketball and the defense is playing their positions really well, point at the ground with surprise in your voice and yell, "Look, a quarter!" Then, while the defense is distracted looking for the quarter, you run past them to the basket and score.
Real skills were taught in the midst of the fun and joking. Thanks to Grandpa and Grandma Farwell for the fun day!
And for the record, The Badger always wins.
