On TV tonight
The Hero, 8 p.m., TNT The contestants have to take a lie-detector test. That could get really embarrassing when producers start asking about who they think will win the show.
SERIES PREMIERE Summer Camp, 8 p.m., USA A reality competition with grown adults pretending to be at summer camp and battling through canoe races and so forth. Break out the mosquito tank and rope-burn contests and we'll watch.
SERIES PREMIERE The Winner Is ..., 9 p.m., NBC Nick Lachey hosts a one-on-one singing competition in which the participants can pick a cash prize if they think they're going to get booted. We hope Nick doesn't perform.
SERIES PREMIERE Hollywood Game Night, 10 p.m., NBC It's summer, so here's a new game show. This one is basically celebrities playing Trivial Pursuit, starting with Matthew Perry and Lisa Kudrow. You'd think David Schwimmer would be the logical choice.
