A baseball doughnut is a weighted ring that fits over the end of a baseball bat, used for warming up during a baseball game. A doughnut can help increase bat speed. Doughnuts can weigh as little as 4 oz. and as much as 28. When you constantly swing a bat weighing 34 oz. and nearly double its weight by putting on a 28-ounce doughnut, the bat will feel lighter when you step to the plate. You should be able to swing the bat faster. This process is known as deceleration training. The doughnut was created by former New York Yankees catcher Elston Howard. Howard, in 1955, was the first African-American player on the Yankees' roster. He played catcher and the outfield during his time with the Yankees. The first team to invest in Howard's product was the St. Louis Cardinals. This essentially got players out of the habit of swinging multiple bats to warm up. While Howard is credited with inventing the doughnut, he did not make the amount of money he had hoped due to other companies making their own versions of the batting doughnut. Howard and his supporters did not have the funds to take the companies to court. During a game, you can find the doughnut lying in the on-deck circle. The player in the on-deck circle normally swings a bat and stretches to prepare for his at-bat. The different doughnuts weigh varying amounts. The doughnut is discarded in the on-deck circle when the player moves into the batter's box. The weight was later dubbed the "doughnut" and the "iron doughnut".

The Donut Man (played by Rob Evans), is a children's songwriter and performer known for his many sing-along audio and video tapes produced with Integrity Music. His DVDs have received six gold and two platinum sales awards from the RIAA. He is called the Donut Man in reference to one of his first songs that included the line "Life without Jesus is like a donut; there's a hole in the middle of your heart". Rob also sings in churches as a children's Bible story songsmith and presents concerts to children and families. His first-person songs put the audience into the shoes of the biblical characters he sings about. The Donut Man's sidekick is Duncan the Donut (a foam donut puppet built by professional puppet company Axtell Expressions, whose creator Steve Axtell puppeteers and voices Duncan).
