[private joker]

God I hate "cute" outgoing messages. When I'm calling someone, I just want to get them so I can speak. If they can't answer, I'm already pissed off and the last thing I need is an amateur stand-up routine. Just say "This is ___ leave a message" and end it right away so you don't waste my time. Furthermore, the same friends will be leaving messages, so even a funny joke will only be funny once -- the rest of the time it will be old and make you look like a douchebag.
