Wit: Tonight's preview performance is also pay-what-you-can to see Margaret Edson's Pulitzer Prize-winning play.

Night at the Museum: Catch pirates, explorers, pioneer women and even the Ghostbusters sneaking around the galleries as kids trick or treat their way through the Tampa Bay History Center's hands-on exhibits while snagging candy from historical figures come to life. Features ghoulish games, creepy crafts and a costume contest with prizes. Starting at 4 p.m. at the museum, 801 Old Water St., Tampa. $14, $9 children; $8, $6 child members. (813) 228-0097.

Night of Too Many Stars: America Comes Together for Autism Programs, 8 p.m., Comedy Central: Finally, a telethon that's both entertaining (featuring host Jon Stewart, Tina Fey, Amy Poehler, Stephen Colbert, Katy Perry and Triumph the Insult Comic Dog) and gets off the air before The Walking Dead starts. That alone makes us want to give them money.
The Walking Dead, 10 p.m., AMC: Well, look at that, the show remembered it has zombies available for episodes besides the season finale. Some exposition is vital, sure, but let's keep severing limbs, shall we?
