In good ol' CS 1.6, I was playing on a custom map (cf_dust - made by cF.TonyDanza) and I happened to be faced with a 5 on 1 at the end of one particular round. I had killed the bomb carrier earlier in the round and was guarding the bomb, and had around 16hp and a Pump Shotgun. I fully expected to be obliterated that round, and figured I'd be welcomed with "nt" from my fallen teammates. Well, the remaining terrorists happened to stick together (smart on their part, as they already knew I was using a pump shotgun). They came at me in a big open area in the middle of the map all at once, with AK fire comin' at me. Somehow, with my Kangaroo-style of Pumping that I had adapted a few months prior, I managed to dispatch all 5 terrorists with 6 shots without getting hit once. It was amazing. Everyone was just like "Holy s***!" Basically from that point on, nobody ever doubted my pump skills again. Good times.
Also, on that same map, a few months back (from now, not then) we had a special event. The clan I'm in had hosted a "Gladiator vs. Shankenstein" event on that map. Basically, it was one Gladiator, who could use any weapon they wanted, vs. five Shankensteins, who were restricted to using only Knives and Grenades.
Apparently, during nearly a dozen outings, the Shankensteins had never been defeated. Well, I flat out annihilated them.
Here's a screenshot of the final score after 10 rounds (I had 35 kills before I finally died once):

And here's my highest damage total after a single round:
