Smash Mouth's lead vocalist Steve Harwell didn't take too kindly to pieces of bread being thrown at him on Sunday night during the finale for Taste of Fort Collins.

He lost his temper when concert attendees started throwing slices of bread in the air. A few pieces reportedly landed on the stage.

Loaves of bread were being given away for free at one of the Taste of Fort Collins vendor booths.
