Tom Grossett is really fast at the drums. He is apparently an "Extreme Sport Drummer." We ddin't know that was a thing, but we do now.
Grossett wanted to a beat a record. He wanted to become the quickest drummer in the world. The record for the world's fastest drummer was 1203 strokes in 60 seconds.
So, Grossett made 1208 strokes in that time. So, that happened.
