Fish Mavericks (10pm, NBCSN) - This NBC Sports Network outdoor fishing show centers on captain Dave Schunke and his crew aboard Fish Circus as they travel around competing in fishing tournaments. It debuted a couple weeks ago with a show in the Bahamas, followed by a show in New Jersey (future episodes focus on Virginia Beach, Louisiana and Alabama). Tonight, in collaboration with the Wounded Warrior Project, the crew goes to New York to take U.S. Army veteran Robert Gill out to fish for striper, where Gill talks about how fishing helped save his life. This sounds very nice and potentially serious, so I won’t make any jokes about a fisherman named Gill.
Naked and Afraid Pop-Up Edition (10pm, Discovery) - Um, no comment.
