The term celebrity is used rather loosely these days, and basically anyone who finds themselves with enough Twitter followers and more than five minutes of screen time calls themselves a celebrity.
But those "famous" faces come marching into our pop culture lovin' lives whether we like it or not, often in the form of a ridiculous cameo appearance that makes the audience cringe.
Of course it's not always the "celebrity" that makes us cringe, sometimes it's the fact that the celeb agreed to do the cameo in the first place that makes us shrug and shudder at the same time.
Remember when Milton Berle appeared in RATT's video for "Round And Round"?
Yeah, I wish I could erase that memory from my mind as well, but it appears we're stuck with that startling image of Uncle Milty looking more like Aunt Miltina for life.
And who could forget Richard Pryor's appearance on The Partridge Family?
I'm pretty sure he spent the rest of his life wishing he could forget he'd ever made a cameo appearance on that show as well.
But in the end the award for most WTF worthy cameo appearance goes to Larry David for his inexplicable appearance on Hannah Montana.
