The World's Most Expensive Skidmarks

Singer Elvis Presley wore underwear.

When Elvis died 35 years ago, some of his underwear needed to be washed . . . but it never was!

And now, a pair of Elvis's dirty underwear is going on auction. According to the BBC:

A pair of Elvis Presley's underpants are expected to reach up to £10,000 [about $15,000] when they are sold at auction. Unwashed and still soiled with stains, the pants were worn beneath one of Presley's famous white jumpsuits during a performance in 1977.

So I'm pretty sure that this makes these the world's most expensive skidmarks! (Or bacon strips. Whichever you prefer.)
