All hail Adrian Pimento, God Emperor of Brooklyn Nine-Nine

Here’s what’s up in the world of TV for Tuesday, March 29. All times are Eastern.
Top picks
Brooklyn Nine-Nine (Fox, 9 p.m.): Every once in a while, there comes along the perfect fusion of show, guest actor, and perfectly, deliriously dumb character name. That time is now for Brooklyn Nine-Nine and television’s most lovable sleazeball, Jason Mantzoukas, who has taken up residence in the precinct as the just wonderfully named Adrian Pimento. Seriously, people: Adrian. Pimento. We’re not even going to pretend to be able to articulate why that name amuses us so much, but tonight’s episode has Rosa trying to get Jake to help win Terry’s approval for her relationship with Adrian Pimento, all while ol’ Adrian Pimento becomes convinced he’s being hunted by someone from his past life working deep undercover in the mob. Sounds fun! And while we’d sure love it for Mantzoukas to hang around the Nine-Nine for the next 3,500 years while slowly transforming into a giant sandworm—LaToya Ferguson would probably feel the same way, if she didn’t have such an overwhelming desire to put a nerd in the Walls of Jericho right about now—yeah, we’re probably near the end of his guest star stint. So tune in and just enjoy the Adrian Pimento-ness of it all while you still can.
The Flash (The CW, 8 p.m.): Barry Allen follows up his universe-hopping jaunt to Supergirl’s universe—which we’re sure he’s totally going to mention tonight!—with a spot of time travel, as he seeks out the old, evil Dr. Harrison Wells to help him get faster, which feels like a real referendum on the mentoring abilities of the new, just sort of grouchy Dr. Harrison Wells. (Come to think of it, this is basically The Flash doing its very own version of Whiplash, so we approve.) Either way, the trip back in time means the show has a not totally contrived reason to bring back Eddie Thawne, who Scott Von Doviak imagines has spent the past year relaxing with Tommy Merlyn and Carter Hall in the Arrowverse’s rest home for blandly handsome, unceremoniously killed-off early-season love interests.
Secrets Of The Dead/Frontline (PBS, 9 p.m./10 p.m.): For those in search of a little culture, PBS has the good stuff tonight, as Secrets Of The Dead examines new evidence that the three prisoners who disappeared after escaping Alcatraz in 1962 might have reached the shore after all, while Frontline investigates reform efforts in Saudi Arabia.
Premieres and finales
Deadliest Catch: Ticking Bomb (Discovery, 9 p.m.): The 12th season of what we are given to understand is television’s most extreme fishing show kicks off with a two-hour premiere. Please be about bomb-swallowing fish, please be about bomb-swallowing fish…
Like A Boss: Fake It ’Til You Take It (Oxygen, 9 p.m.): Who among us has not been faced at one time or another with some impossible dilemma, some all-encompassing moral conundrum that would force us to compromise all we hold dear and sacrifice our last vestiges of unsullied humanity? It’s just that not all of us have that moment televised on Oxygen. To wit: “Amber struggles with a decision to work for Nick Cannon in the series premiere of this reality show that zeros in on four assistants to top power players in Atlanta.” Struggles. To work for. Nick. Cannon. [Shudders.]
