Coolest Crash Dialog ever
I've been using the Adium Instant Messaging Client lately - it's a mac only universal client based on the GAIM engine so it can interoperate with AIM, Yahoo, MSN as well as Jabber based servers like GTalk and many corporate IM servers. It also offers Off The Record (OTR) messaging to allow end-to-end encrypted conversations using insecure IM services like AIM. The other day it crashed - it's been pretty rock solid up to this point so I'm not too concerned. The crash dialog above is the coolest I've seen - it helps to know that the mascot for Adium is a duck.
