Here’s a Penn and Teller by Mike Warden.

They’re notable members of the skeptic community, and enjoy disproving beliefs they think are untrue.  Because of this, their show seems to be of the love-it-or hate it variety, which is working well for them.  they’re the most popular comedy-and-illusion act on the Strip.

While this caricature isn’t as chock-full of gags as his regular work, it’s spot-on for expressions.  A lot of advertisements for Penn and Teller feature them maiming, dismembering, or casually killing each other for our entertainment, so this disembodied-head-as-balloon trick isn’t too far off base.  In fact, I wouldn’t be surprised to see them do this in their actual act.
