He Flat-Out Stated That He Was Steamrolled Into Doing It

I can't make this stuff up:

DARE YOU TO DO IT

At about 3:30am, on Sunday, September 23, 2007, officers from Area D-14 (Brighton) responded to a radio call for a fight at 15 Pratt Street. On arrival, officers observed a small group gathered in the middle of the street. Officers spoke to the victim who stated that an individual, after being dared, jumped into the seat of a steamroller, started it up and, then, drove it into his car. Officers observed minor damage to the bumper of the victim’s car. When speaking to the suspect, officers observed that it appeared the suspect was under the influence of alcohol. Officers arrested Matthew Gilman, 22, of Allston and charged him with the Destruction of Personal Property and Larceny of a Motor Vehicle.

You can say the vehicle was pressed into service. The police officers got the ball rolling by taking him down to the station.
