Don't Pleather the Hoff, Pleeeeze!

David Hasselhoff sang "Hooked on a Feeling" at a benefit last night, but the feeling clearly is not fashion forward.

The Hoff sang his "greatest hits" at a benefit show last night at Molly Malone's for the family of a friend who died from cancer ... great cause, but dude, you're kinda cool again. Lose the shirt.
