This is my preferred take on the Perforated Q&A: participants are called by their numbers, and the performer reads their minds.

It is that simple, and you probably already have all you need to perform it by the end of the day (please don’t; rehearsals are important, especially for something as dependent on delivery as Q&A).

This particular version comes complete with Julien Losa’s preferred switching choreography, requires no gimmick, and solves Bob Cassidy’s quandary with the method—introducing logical disconnects so that no one can suspect you of secretly reading their questions. This is something that can be ported to any take on this particular Q&A method!
