Bill Murray is really getting into this whole "Being Billy Murray" thing. After he made an unexpected appearance at a bachelor party last month, he's back.

A couple was taking their engagement photos in Charleston, SC, when the photographer says:

Gauba, used to tourists and onlookers sometimes heckling his shots, said he told Erik Rogers and Ashley Donald to look at the camera but they continued to look behind him in stunned silence.

"I thought who the heck is bothering them," Gauba said Wednesday. "I turn around and it's Bill Murray with his shirt up, belly out, tapping his belly and trying to make them laugh."

Murray, who recently made national headlines when he gave some advice to a visiting bachelor party, accepted Gauba's invitation to pose for a shot with the couple.

"Sure I would," Gauba recalled him saying. "I took the shot and off he goes."

I guess this is what he's doing instead of Ghostbusters.
