Wonderbat
Wonder Bat is the name that Homer gave to the homemade "magic bat" that he used while playing for the Springfield Nuclear Power Plant softball team.
Creation
According to Homer, "It all started last year during a terrible thunderstorm, when I locked myself out of the house. Sheltering myself with a large piece of sheet metal, I ran for cover under the tallest tree I could find!" A bolt of lightning struck the tree, and a branch fell down. "Something told me this was a very special, very magical piece of wood that I could make a bat out of." So, he put his homemade football on hold and made himself a bat.
Softball team
When his co-workers are hesitant to play softball, Homer motivates them by saying he has a secret weapon. They decide to sign up. During the team's first game, the plant falls behind 5-2, with three men on base and Homer up to bat. Homer reveals his secret weapon, and is mocked by his team mates. However, Homer manages to hit a home run, and this starts a winning streak. Eventually, his team mates try to find their own magic bats, with Carl trying a piano leg and Charlie using a prosthetic leg.
However, Mr. Burns eventually replaces the team with Major League ringers. Homer believes he has nothing to worry, as long as he has Wonder Bat. However, the bat is broken in half by a pitch thrown by Roger Clemens.
