What Would Ryan Lochte Do? 10 p.m., E!
Apparently “a reality show” is one of the answers to the titular question. The five-time Olympic gold medalist bellyflops into shallow waters with this series that chronicles his life in Gainesville, Fla., which, at least as compiled and edited here, looks painfully tedious. Lochte (above) trains, pals around with his “Lochterage” — yes, this is what they call his “entourage,” including his brother and an assistant — gabs with his mother and sisters, and generally acts like the goofy Lochte that the people who find him endearing (and hot) have come to love, and the people who mock him have come to mock. Considering how often he is shirtless or in a swimsuit and how often he speaks, both groups will have plenty to do.
