I'm afraid not. I'm aware of medicine shows, in which people would try to sell things like "miracle cures" between entertainment bits.
No, I dont know of any shows, but I think theres a movie called Se7en. It has Jjim Carey in it if im not mistaken. I really like medicine shows though. Theyre touring acts  that help heal people between different kinds of entertainment. Its actually reall cool
Seven is my favorite number! That's great! Speaking of 7, since 1997 Eric Jacobson has been the primary performer of Bert. I did not know that! Do you know why other people think it's a lucky numbe? I'm not sure. However, I do know of a character on General Hospital named Lucky Spencer. That would be a neat name, does Lucky like the number 7? I don't really know. What I do know is that he was cast in 1993, his birth having been announced in 1985. Do you know if there are any shows based on the number 7?
Medicine shows were touring acts (traveling by truck, horse, or wagon teams) which peddled ''miracle cure'' patent medicines and other products between various entertainments.
