It's Always Sunny in Philadelphia Season 4 Episode 1
Mac and Dennis: Manhunters
Charlie and Dee have been stealing Frank's delicious meats, so Frank leaves out human meat to get back at them. Driven by their cannibalistic needs, Charlie and Dee go in search of human flesh. Mac and Dennis harass Frank for hunting defenseless animals and think it would be much more badass to hunt something that could fight back ... like a human.
