The worst thing you can do to Stanhope is to just ignore him.
BTW, I was there for bar trivia and his act just happened to be scheduled after it. Bought one CD of the band who opened for him, listened to it and and had to go back and hear some more of them. Bought their other CDs also. Stanhope may have some stuff they were also selling but I didn't care. Funny thing is the band was there because they liked Stanhope and wanted to help him out.
