Singing or otherwise blasting music during a multiplayer match is one of the great sins of online gaming, but every once in a while an exception can be made. According to YouTube user Sinj, the player singing in this round of Call of Duty had no idea his mic was on. It's funny to hear "Jay13SamoaTOA" stumble through some of the lyrics but still belt it out like no one is listening. He even got a nice response from his teammates. 

It went well this time, but don't use this video as an excuse to broadcast your terrible taste in music in future online games. You might think it's cool or funny, but make no mistake, you are not this guy -- you're just a tool.
