The funny thing with ZZTop.
The guy with the last name beard, didn't/doesn't have one.
Speaking of ZZTop, I think Gillette made a similar offer to the bearded guys, if they'd use their razor to shave them off. IIRC, it was a million bucks as well. Obviously turned down.
The beards would of course grow back, but it would take YEARS to get that long again.
