It’s Always Sunny in Philadelphia (FXX, 10:00 p.m.) — Boxers joke that time is undefeated because even the greatest champions wither in their old age. Frank learns this lesson the hard way as he tries to keep pace with the gang’s younger maniacs.
Law & Order: SVU/Chicago PD (NBC, 9:00 p.m.) — A special, two-part, back-to-back crossover episode that focuses on a nationwide manhunt for a pair of killers who escape from prison.
The Middle (ABC, 8:00 p.m.) — Brick lets a little power go to his head when he taps Cindy and Troy to act in a school project, while Mike and Frankie have their Breaking Bad-“Fly” moment while trying to figure out which appliance a loose plastic piece belongs to.
Arrow (The CW, 8:00 p.m.) — Nyssa goes full Godfather and makes Oliver an offer he can’t refuse and Malcolm dads out to help his daughter.
American Idol (FOX, 8:00 p.m.) — Half of the contestants sing their guts out in the first showcase round.
2 Broke Girls (CBS, 8:00 p.m.) — Turns out that Max and Caroline are famous video game characters, and now they’re looking to be compensated for their likenesses. Yeah, them and every college football player from the ’90s and ’00s, amirite?
The Mysteries of Laura (NBC, 8:00 p.m.) — Valentine’s Day means it’s time for chocolate, teddy bears, maybe some (un)comfortable undergarments and, obviously, resurfacing serial killers.
The Goldbergs (ABC, 8:30 p.m.) — Beverly and Murray play a little good-cop-bad-cop when Adam wants to go see the R-rated classic, Porky’s.
Mike & Molly (CBS, 8:30 p.m.) — Mike takes issue with how Molly’s budgeting her time and tries to nudge her toward being a little more Susie Homemaker. His suggestion will surely be well articulated and she’ll definitely absorb his constructive criticism with full rationality.
Criminal Minds (CBS, 9:00 p.m.) — The BAU is on the hunt for the suburban Gary Heidnik when an 18-year-old girl escapes from a house where she’d been held captive with other women.

Suits (USA, 10:00 p.m.) — “The enemy of my enemy is my friend … unless he disagrees with how I should try to defeat my enemy.” Mike and/or Harvey, probably.
