The performance of "Mule Train," as always, demands an assistant from the audience, since the clapper must be clapped with each "hyaah." Previous experimentation with affixing the clapper to JB's inner thighs resulted in a disaster that I'd rather not get into, so all were thankful when the birthday lad's wife, the lovely (and fetchingly 80's-attired) Jill, heeded the call to clap.
