What's on TV tonight?

For better or worse, Thursday night channel surfers will be treated to yet another deluge of summer reality TV shows.

The fun starts at 8 p.m., when voyeurs can opt for either "Pirate Master" (CBS) or "Fast Cars & Superstars" (ABC). My bet is on the latter. You really can't go wrong when you put celebrities in stock cars. Well, actually you can. But sometimes in reality TV, going wrong feels so right.

Plus, the show stars singer Jewel. If hitting a race track won't save your soul, what will?

Also at 8, Fox will show a new episode of "Are You Smarter Than a 5th Grader?" I, meanwhile, still haven't deciphered the difference between a rhombus and a trapezoid.

At 9 p.m., the network offers an hour-long episode of "So Y ou Think You Can Dance." Two of the top 20 contestants will be voted off.
