The show is falling apart, for no reason. Seems every episode they are throwing in some 'Chumlee messing things up' humor. But smashing that glass really ticked me off. I know it's a drop in the bucket for history, but someone may have actually wanted that machine. They aren't making 1950's bowlers anymore, and now there's one less.
Hopefully they leave American Restoration alone.

Brokedad is right, they shattered the original backglass. You could see the art in the pieces laying all over it.
I thought the concept of the 'History Channel' was to preserve history. What's next, maybe Chumlee can wipe his fat ass with a presidential document, or crash a Shelby Cobra into a garage door? That would be hilarious.
If I wanted to watch people being morons, I could watch 'Hardcore Pawn'. Pawn Stars used to be a higher standard, every episode I learned something. But once again another network caters to the low-brow community.
