What’s On Tonight: Mr. And Mrs. Leslie Knope Invite You To Their Wedding

Parks and Recreation (NBC, 8:30 p.m.) — I’m gonna lose it when Ron toasts Leslie.

Community (NBC, 8 p.m.) — “The study group,” and Battlestar Galactica‘s Tricia Helfer, “goes to the annual Inspector Spacetime Convention,” where, presumably, self-referential fandom references run crazy. WHAT IF PIERCE IS A CYLON? I’d be down for that.

Scandal (ABC, 10 p.m.) — It’s been a season and a half, and I still have no idea what Scandal‘s about, other than scandals. And even of that I’m not sure, though I do know tonight’s episode, “Boom Goes the Dynamite,” means next week’s will be called “Jib Jab Evolution of Dance.”

Archer (FX, 10 p.m.) — A snake bites Archer in a “special place.” It got him on the crawl space behind the fridge?

Legit (FX, 10:30 p.m.) — Ramona asks Jim to be a mentor to her nephew, the world’s youngest raging alcoholic.

LATE NIGHT GUESTS: Johnny Depp on Letterman; Arsenio Hall on Leno; Kelly Ripa on Kimmel; Kunal Nayyar and Molly Shannon on Ferguson; Stephen Colbert, Anthony Anderson, and James Adomian on Fallon; Mila Kunis and Chris Hardwick on Conan; Steven Brill on Stewart; and Lil Buck on Colbert.
