At Gutenberg! The Musical!, Gad and Rannells mock "those f**kers at Merrily" for raising so much money. One night, the cameo guest "Producer" was Christopher Sieber. He came back out, and they started to auction an actual Producer hat from the show. The price was rising, so they began to rub the hat on various body parts, and the price kept rising. It turned into a great skit, that went on for about fifteen minutes with lots of laughs and they sold two hats for over $1,000. The following week, Steve Martin and Martin Short were the cameo guests at Gutenberg, and the crowd went wild. They could've raised a ton on money, but didn't come back onstage after their brief cameo.
