Professional party-crasher Bill Murray popped up once again this weekend, injecting his magnificent Murray-ness into a birthday celebration for Charleston native Marvin Larry Reynolds.

Reynolds reportedly invited the celebrated actor to join him for a joint birthday celebration, since Murray will celebrate his own birthday this month as well. Murray's friend, chef Brett McKee, was catering the party -- which is why we can now all enjoy this fantastic video of Bill getting funky as the evening wore on.

The actor owns a home in Charleston and seems to be spending a lot of time out and about there lately, making this basically the best year ever for sightings of Bill Murray in the wild. Keep your eyes peeled, South Carolinians! He could be anywhere!
