When you put out parody singles for 35 years, you're likely to be accused of repeating yourself once or twice. But I think it's fair to say that Weird Al Yankovic has truly outdone himself with his new video "Tacky," a parody of -- Can you guess? -- Pharrell's "Happy."

The goofy one-take video features some very funny quips about tacky behavior ("Got my new resume / It's printed in Comic Sans" and "I would live-Tweet a funeral / Take selfies with the deceased" are my favorites) and enough celebrity cameos to rival Moby's "We Are All Made of Stars." Look out for Margaret Cho, Aisha Tyler, Eric Stonestreet, Kristen Schaal, and Jack Black, all in flawless apparel.

(My votes for the other best Weird Al videos are "The Saga Begins" and "I Lost On Jeopardy!", for what it's worth.)
