The Happy Deagle Ace in DreamHack Open London 2015, where ENVYUS's Vincent "Happy" Schopenhauer managed to get five consecutive kills on Inferno B site. He got no less than four one-deags, most of which are through a smoke. The deagle flicks in between the shots just makes it even better.
Successfully defused the bomb with only miliseconds left before exploded. Bonus point if managed to defused without a kit.
