American Idol (FOX, 8 p.m.) — The final American Idol is revealed on the series finale of the long-running singing show. That was a fun 15 seasons. Right, you guys?

The Catch (ABC, 10:00 p.m.) — Valerie’s ex has the team digging into big pharma after a trial MS treatment goes wrong. Should have just had Mrs. Bartlet treat it, amirite?
Archer (FX, 10:00 p.m.) — Brace yourselves for butt-fumble jokes, probably, because Archer and Lana are making a handoff.
