“The Gong Show” (10 p.m., Comedy Central): Offbeat acts are evaluated by celebrity

“The Gong Show” (10 p.m., Comedy Central): Offbeat acts are evaluated by celebrity judges in this revival of the old show that is now hosted by Dave Attell.

“Reality Bites Back” (10:30 p.m., Comedy Central): “Reality Bites Back” is a reality show. No, “Reality Bites Back” is a satire. You’re both right! Comedy Central presents its first unscripted competition series, with 10 comedians vying for supremacy in parodies of some of TV’s most popular reality shows. Among the spoofed are “American Idol,” “Survivor,” “The Amazing Race,” “The Biggest Loser” and “So You Think You Can Dance” (re-imagined here as “So You Think You Can Dive,” with contenders getting 24 hours to become Olympics-worthy champs). The opener offers a “Big Brother” spoof in which the cast is forced to live with their mothers for four straight days. Michael Ian Black is host.
