Need a cure for a bad case of the Mondays? Tune into Turner Classic Movies tonight, when Cato H.L. Mencken Research Fellows Penn Jillette and Teller take over as special guest programmers.

A quick look at what Penn & Teller have spooled up:

• 8 PM—The Marx Bros.’ underappreciated 1939 film At the Circus
• 9:30 PM—Orson Welles’ controversial 1976 documentary F for Fake, about the brilliant forger Elmyr de Hory
• 11:15 PM—MGM’s disturbing and highly controversial 1932 film Freaks
• 12:30 AM—Neil Simon’s 1975 Vaudeville tribute The Sunshine Boys, starring Walter Matthau and George Burns (with then-little-known F. Murray Abraham in a supporting role).
