Bruce Willis Shows Off His Lady Gaga-Inspired "Meat Hairpiece" (VIDEO)

Actor Bruce Willis is a bald, bald man. He's been bald for so long (or had his head shaved to hide it), that we can barely remember the days when he had a full head of hair.

So on the new 'Late Show' (11:35PM ET on CBS), Bruce decided to fix this problem once and for all. He showed up wearing a "meat hairpiece": a tribute to Lady Gaga's "meat dress" at this year's VMAs.

To his credit, David Letterman instantly noticed that there was something different about his friend. He just couldn't quite put his finger on it. "You've dyed your ... hair?" Dave said questioningly. Bruce went on to explain the concept of his meat hairpiece. "It's 100 percent ground beef sirloin," he said. "Top shelf, organic." Ooh, classy! Sounds expensive. But then, we wouldn't expect a wealthy actor like Mr. Willis to buy a cheap meat hairpiece.

Next -- and you had to guess that things were heading this way -- Willis pulled out a salt and pepper shaker, and said this to Dave: "Have you eaten?" Oh no. ... But yes, the inevitable then occurred. Letterman ate raw meat off of an actor's head. Immediately afterward, he rushed backstage to barf. So we guess that Dave throwing up is just one more thing that we can blame on Lady Gaga, in a roundabout sort of way.
