He's an insult comic in the mold of Don Rickles, but without as much talent. Toss in a little Italian goombah image that he swiped from Andrew Dice Clay. All that equals a show that's not the greatest, but not bad either. Worth seeing at least once. Ticket prices are maybe a little high for the strength of the show, but not outrageously so.
For the price, though, I probably prefer George Wallace's show at the same hotel.
