Dude...did Bill Murray sing karaoke with us last night?

That's what a group of New York City pals were likely asking themselves when they woke up with photos of themselves drinking and singing karaoke with the star at NYC's Karaoke One 7 club. One of partiers told humor blog The Chive they saw Murray sitting alone with his date and asked him if he wanted to join them in singing a couple tunes.

Unexpectedly, Murray came over and joined the party, even crooning Elvis Presley tunes. Needless to say, the band of twenty-somethings had a hard time believing it was all actually happening.

But they've got the photos to prove it:

Since last year, Murray's been rumored to crash house parties late at night in Brooklyn's artist-loft-laden East Williamsbug neighborhood—loading his pockets with cans of beer and sneaking away as the sun came up. Sounds like this time around, he just wanted to sing some King.
