A camera crew has been following a mystery man in a bad wig around the MGM Grand for a week.
Some of the hotel's 9,000 employees have their suspicions. They're getting a lot of hints to connect the dots to a reality show.
So far they've ruled out The Situation from "Jersey Shore."
The guy in the wig and glasses has been filming what appears to be on-the-job-training scenarios.
He's been in the casino, working the blackjack and roulette tables in uniform, at the front desk, working with security and hanging out with the staff at Studio 54.
The unkempt wig, which comes down to the top of his ears, isn't fooling anyone, according to one spy.
"A tourist walked by and said, 'nice rug,' " an employee said Thursday.
Someone overheard that the guy in disguise is staying at a nearby Super 8.
If the MGM Grand sports book were taking bets, smart money would be on Scott Sibella, the new president and COO of MGM Grand.
And the show?
Bet the mortgage, if you still have one, on CBS' hit show "Undercover Boss," which airs at 9 p.m. on Sundays (KLAS-TV, Channel 8).
