"Eat It" is a 1984 song by comedy music artist "Weird Al" Yankovic. It is a parody of " Beat It" by Michael Jackson. The track was both a commercial and critical success, earning Yankovic a Grammy Award.
According to Yankovic, when he presented his lyrics to Jackson for review, he didn't know what kind of reaction he'd get. Jackson allegedly thought it was amusing, and agreed to allow the parody. On October 19, 1989, the RIAA certified "Eat It" as a gold single.
Eat It is the sixth album by English rock group Humble Pie, released in 1973. A double album, it reached #13 on the Billboard 200, and #34 in the UK.
