Bill Murray at a Cubs game? That's expected.
Getting Bill Murray to break the news to your parents that they're going to be GRANDPARENTS? That's a little on the unexpected side--
Bill Murray has a habit of showing up in unexpected places, doing unexpected things.
Like your engagement photo shoot....
He's even been known to crash a batchelor party, where he gave advice on finding the right girl to marry (pardon a bad word or two... not from Bill, but the batchelors)
Bill also does a real live version of Nick the Lounge Singer...
And he's been known to take over the bar if things get a little hectic. (Note: He won't necessarily give you what you ordered... do you care?)
