My funniest L4d moment was when i was the only survivor left on versus in No Mercy and I made it to the safe ROOM. Mind you there was a full infected team and a tank and they still couldn't get me. That was my coolest moments. Post yours.I think mine would be the time I set up near a wall in the construction area of the  no mercy building as a boomer. The survivors came by, stared at me for 10 seconds then blew me up blasting all of them over the building. They were left hanging while I danced around.When I encountered 2 Tank.Not really my coolest but my most funnyest I was the tank on Dead Rain and i turned around the corner and saw a car so i hit the car and it went flying past the survivors i hit it again and it LANDED in a tree and i couldn't get it down

I have a picture of this on my STEAM account: Bromthemanmy best moment was when me and a friend was messing around on a lan server in l4d, USING the console to no clip and spawn some infected, so we decided to spawn in 50 witches and i got bored and threw a petrol BOMB down, the sound alone was terrifying, ( it cashed both the pc due to t hem been low spec office pcs) but it was worth it
