I had the privilege of interacting with a charming and well-mannered bachelor party recently - the groom's note says it all.
(No, seriously, they were actually charming and well-mannered, hence this thank-you from the groom. Sure, they all came in loaded and loud, but I wasn't asleep anyway. My only annoyance was that since Dave failed to warn me that he was bringing the entire party back to our house after the bars closed, I was wearing my giant disgusting bathrobe when a dozen dudes trooped through the door. No one cared but me, of course.)
