I decided to play Leroy one night in WoW. I was with a friend of mine who'd just made 80 on his warrior and needed to grind heroics for his entry tank gear. So him, another guildy, and myself grabbed two random schmucks from trade chat to round out our group.
We were about 3 dungeons in when we got to Drak'Tharon Keep. Before we pull the first group my friend and the other guildy start bickering over trash mechanics and at least one of our two people from trade chat goes afk. About five minutes goes by and something, I'm still not sure what, compels me to shout in vent "Less talking more pulling! RELEASE THE HOUNDS!!!" at which point I popped spirit wolves, shamanistic rage, heroism, and proceeded to attempt tanking the first trash pack.
Suffice be said there was a beautiful moment of silence with a subtext of "....wtf just happened?" and after that initial shock wore off everyone jumped in and we cleared the pack. No, it wasn't a Leroy wipe of the group (which wasn't exactly my goal I was just getting impatient) but it's still one of those legendary moments amongst my friends and guildies I still play with.
