We all remember Weird Al Yankovic, thanks to his videos for "Eat It" ("Beat It"), "Like a Surgeon" (Madonna's "Like a Virgin") and "Smells Like Nirvana" ("Smells Like Teen Spirit"), which played on TV back when music video stations actually still played music videos. Yankovic even won a Grammy for the video for "Fat," his parody of Michael Jackson's "Bad." Now he's back and he's laying into Lady Gaga. Originally she denied him the right to lampoon the song, but then they made up and Yankovic agreed to donate the proceeds of the song to the Human Rights Campaign. Hilarious and heartwarming.
