It's one thing to call yourself an ELVIS PRESLEY fan. But if you're willing to buy a pair of the guy's STAINED UNDERWEAR, you've taken fandom a little too far.  And if you're willing to pay $16,000 for said stained underwear, you need help...

A British auction house is selling a pair of stained tighty whities that Elvis wore back in 1977, so people wouldn't see panty lines on his infamous white jumpsuit.

 The underwear is even described in the auction listing as, quote, "unwashed with some stains apparent."  HA!

 The auction takes place on September 8th.
