What to Watch Tonight: Alphas, Switched at Birth, and the Final Presidential Debate

What to watch on Monday, October 22...

Hey you! Yeah, you—the one with the bumpy, grumpy mad-face. Don't be bummed that it's Monday, because tonight brings with it the third and final presidential debate! Which, if you're into politics—hey, you get to watch a presidential debate tonight! And if you're not into politics—hey, after tonight there won't be any more presidential debates to mess with your TV lineup! Of course, baseball might still mess with your TV lineup. But hey, if you're into baseba—what? You just want to know what else is on tonight? Right. Okay:

8pm, The CW
In "It's All Fun and Games," the gals get into some "irresponsible fun"... which appears to involve Adrianna encouraging Silver to do some kind of bungee-cord thing on the beach. Meanwhile, Alec smooches on Naomi. Oh, and there's also some detective asking about Vanessa's whereabouts. Ruh-roh!

SEASON 2 FINALE, 8pm, Syfy
Fans of Summer Glau will get another dose of the actress in tonight's Season 2 finale of Alphas, "God's Eye," in which a desperate Dr. Rosen tries to track down Stanton Parish for some final words (intense!), all while suffering vivid hallucinations of his daughter. Meanwhile, the rest of the team members find themselves battling time in order to stop the immortal villain from carrying out his deadly plans (mwaahhahaha!).

SEASON 1 FINALE, 8pm, ABC Family
Switched at Birth
In tonight's season finale, "Street Noises Invade the House," Bay and Zarra find themselves in a dangerous situation. Meanwhile, the big trial with the hospital ends with a shocking conclusion and the relationship between Daphne and Jeff is revealed.

RuPaul's All Stars Drag Race
Many of your favorite queens in the history of RuPaul's Drag Race will return for the ultimate drag competition in tonight's premiere of RuPaul's All Stars Drag Race. Who's excited?

LIVE, 9pm Eastern/6pm Pacific, NBC, ABC, CBS, FOX, CNN, MSNBC, C-SPAN, PBS
Presidential Debates
The third and final debate! President Barack Obama and Republican presidential nominee Mitt Romney will square off one last time tonight at Lynn University in Boca Raton, Florida, so we can only assume there will be plenty of cringeworthy confrontation between the candidates to cap things off before voters head to the polls in November. "Face the Nation" host Bob Schieffer will moderate.

10:30pm, MTV
The Inbetweeners
In "Reading Gives You Wings," our boy Simon tries to school his girlfriend on her stealing habits. Meanwhile, Will organizes some kind of protest against the school library. And maybe something about Red Bull, if the episode title is any indication?
