Thank you toby for answering my original question
and thank you craig
Im not into coin, or rope magic...and for large crowds a good mentalism routine will work wonders.
With that logic why don't you just run out and pick up an Asrah?
You have the idea of Mentalism in your mind, most likely because it's what "everyone else is doing" . . . there are some great comedic bits you can do like Bob Cassidy's UFO or John Rigg's "Procrastinating Prognosticator" . . . both are hilarious (especially the latter) I've used both and had people on the floor with them and while the Rigg's routine means you need to do some creative photoshopping so as to make up the tabloid covers, it's well worth it. Lee Earle has a ton of great Mental Magic routines in the SYZYGY series that fit your parameters as well BUT, you don't yet have the chops to pull them off . . . or so I'd assume given that you don't seem to know anything about Mentalism as of yet. . . Had you read Corinda, Annemann and even Karl Fulves you would already have foundation material that you could spin . . . you're looking for a short cut -- a TRICK, not Mentalism.
Mr. Butterfield, the majority of acts that parody Mentalists do so in a manner that put down the art. The Great Karnack (Johnny Carson) did a fun and tasteful Parody and there are others (sadly, my brain is shorting out and I can't recall names). It's difficult for most, especially an inexperienced individual, to pull off this kind of tasteful persona. . . and no, I don't take some of the bits others do very well in that they honestly do hurt certain forms of mentalism and those of us that perform in said manner. I guess I'm a lot like shut-eye Dowsers & Phrenologist when it comes to such things.
Understand. . . humor is vital to a good mentalism show but so is believability. Every time someone does an act that makes a Mind Reader look dumb, it hurts the craft. Maybe I'm being too touchy on the subject but I have the obligation to steer people away from that sort of comedy vs. accepting it.
I must emphasize to the OP that Mental Magic is the area they want to research, it is where they will find the kind of gag they are looking for. I would also suggest doing a google search on Comedy Mentalism and check out the sites of those performers that are working just such an act. I just did that very search trying to find a certain performer's video; I couldn't find him but I found hundreds of pages that cover this very topic.
