I used to own a somewhat scandalous autograph (but I lost it at some point). It was from Ron Gallagher, who ripped off his famous brother’s routine (all of the jokes and all of the watermelon smashing) and advertised himself as Gallagher II: The Living Sequel, which led to much fighting in and out of court. I got to sit in the front row of what was technically a Gallagher show, so I was happy at the time.
