(Editor's note: This column was originally published on July 13, 2017.) World-renowned illusionists Penn Jillette and Teller return this week to The CW for a fourth season of their series Penn & Teller: Fool Us. Hosted by Alyson Hannigan (pictured at top center with Jillette, left, and Teller), the show puts the spotlight on aspiring magicians who perform their trickiest tricks. Jillette and Teller then try to figure out how they were done. Anyone who successfully stumps the guys wins an opportunity to share the stage with them during their show at the Rio Hotel & Casino in Las Vegas.
