Someone in the crowd threw bread at the singer and he lost his sh%t.

I remember years ago I saw an interview with Smash Mouth and he was talking all kinds of trash about Alice in Chains. He was saying that his band was not like AIC and that they didn't bring negativity into the world with music or lyrics. I guess Smash Mouth has changed now that they are washed up. They don't mind calling the crowd P*****'s even though it was a family event full of kids. Classy! NSFW.

Do not get me wrong I get it that he was mad about things being thrown at him but seriously he has dealt with this before and this is not the way to win a crowd over.
