Once upon a time, My sound drivers were somehow deleted, so, no sound.
After attempting to tinker a bit, I decide "Fuck it" and start up Team Fortress 2.
Team Fortress 2 can be difficult without sound, but I'm a very experienced player and it wasn't the first time I've played without sound. So I join a server I used to frequent, which has All-talk enabled.
"Wait a minute," you're thinking, "Why would All talk being enabled mean anything if you don't have sound?" Well, I'll tell you numbnuts, let me finish.
For some reason, with my sound drivers deleted, when people turned there mics on the presumably toss insults at eachother, the game never registered them as turning off. So after about 10 minutes of playing, 80% of the server had permanent exclamation points above their heads. Even Cloak and Dagger spies.
Now, I wasn't gonna to let any of those dirty spies into my base, so I attempted to make it look like I was finding them by accident. One very angry individual caught on though, and accused me of cheating (Which I kind of was) and, while I attempted to explain myself, got banned from the server.
T'was an interesting experience.
