Many professional athletes have pre-competition rituals or quirks, but NASCAR driver Tony Stewart has one of the strangest ones we've heard of.

Some athletes wear a special outfit, others have a lucky charm, a handshake, a chant. Before each race, Tony's tradition is to grab the rear end of someone on pit row. Last Sunday during the Geico 400 at Chicagoland Raceway, Stewart decided to seek out the wife of Kevin Harvick to perform his pre-race ritual.

Stewart snuck behind Delana Harvick while she was talking to a couple of crew members and grabbed two fistfulls of Delana's behind.

Tony's butt grab provided a great deal of entertainment to the ESPN pre-race crew, and even got analyst Brad Daugherty to drop a "no comment".
