Imagine the doors of your office elevator opening to reveal an Elvis impersonator. Now imagine that Elvis impersonator is Channing Tatum in disguise.

That’s exactly what happened to the luckiest people in the world this week. Tatum put on the classic sequined jumpsuit and black wig, dancing and crooning to some of the building’s unsuspecting — and slightly weirded out — employees.

And it was all for a good cause, because in addition to being one of the most handsome humans on the planet, Channing is practically a saint. He’s teamed up with Omaze and (RED) to encourage people to donate $10 to the fight against AIDS and enter to win a trip to Las Vegas to attend the premiere of Magic Mike Live with the OG Magic Mike himself.
