I do a variation on the classic “Memory Thief” routine
This is a trick I’ve actually done several times before at open mics and a few shows, but I’ve never been able to share a successful version until now. The reason actually pertains to the joke I make during the set-up: I tried it with audience members who HAD drank too much and weren’t able to remember any of the symbols. And when I saw Donald coming up with his beer bottle I was worried this would lead to another incident like those. Thankfully my fears were unfounded, and this turned out to be the best attempt so far.
