For me it would be stuff like The Young Ones, Monty Python, Blackadder, old Simpsons, South Park, Curb Your Enthusiasm, Beavis and Butthead (especially their commentary on music videos... one of the best ones being the one they did for the Poison video, hahaha!), Cromartie High School (especially the episode about trolling), The Whitest Kids U Know, Married With Children, Chappelle's Show (Clayton Bigsby, hehehe), Aqua Teen Hunger Force, and Monkey Dust.
And for movies, Fletch, Idiocracy, Tunnel Vision, Airplane, Spinal Tap, Fear of a Black Hat (the rap version of Spinal Tap), and Happiness are a few that come to mind.
Checked out some of the stuff mentioned here and got into Peep Show, Bob's Burgers, Nighty Night, and Garth Marenghi's Darkplace.
