Metro's Wednesday night TV breakdown.


‘It’s Always Sunny in Philadelphia’
COMEDY. Charlie undergoes a weird experiment that makes him really smart, really fast in this episode titled “Flowers for Charlie.” It’s like “Flowers for Algernon,” get it? (If you don’t turn off the ‘tube and read a book, ya illiterate boob!)
10 p.m., FXX


‘Duck Dynasty’
REALITY. Tonight, the redneck gang of waterfowl hunters host a Halloween party, which probably includes activities like bobbing for Ho-Hos in a bucket of Colt 45, or something. Incidentally, did you all know that “Duck Dynasty” is one of the most popular Halloween costumes this year?
10 p.m., A&E


‘Top Chef’
COMPETITION. Tonight, the “chef-testants” vie for food domination in a Vietnamese challenge. The guest judge is badass chef personality and owner of NYC’s Baohaus Eddie Huang, who's a pretty cool dude.
10 p.m., BRAVO
