Bill Murray is pretty much the man.

We have read stories about him randomly crashing frat parties, buying rounds of drinks and doing the dishes. Then, as quietly as he arrives, he disappears into the darkness and whispers to someone: "No one will ever believe this story."

While dining at a restaurant in Charleston, S.C., recently, Murray learned of a bachelor party taking place in one of the other rooms.

After declining a round of drinks from the bros, he decided to make an impromptu appearance and gave a surprisingly heartfelt speech with some great marriage advice for the future groom.
