Wednesday night, the reality series Penn & Teller: Fool Us premiered to a 0.5 adults 18-49 rating, making it the CW’s highest rated new summer series by a huge margin. (The premieres of Backpackers, Seed and Famous in 12 all earned a 0.2 adults 18-49 rating.) Like Penn & Teller: Fool Us, Masters of Illusion is about magicians. Will it also pull high (for CW in the summer) ratings out of its hat? If it does, will it, Penn & Teller:Fool Us, and Whose Line Is It Anyway inspire the CW to adopt the marketing slogan “We keep our shirts on in the summer?” Make your predictions!
