Berman opened his mouth too wide too many times and Pete told him to step back and let it be. Berman pushed Pete into his sled and broke his windshield. All hell broke loose and Berman needs two new teeth and probably a clear face mask to get his nose back in place.
I've seen Pete get out of hand unprovoked, but this time was justified.
Berman to make a Long Story Short: you got served!
