Sure, you can tase a shark, magic yourself into a chopper and even survive having your weapon shot up, but there's one glitch in Grand Theft Auto V that the folks at GTA V Mythbusters found that is absolutely hilarious, and it involves punching yourself in the face.
When you log out of GTA V, you're then represented for a brief period of time by a non-player character or NPC. Turns out that if you quickly log back in, you can find that NPC near where you logged out and repeat the process multiple times, thereby copying yourself.
Getting them all together and watching them fight will likely be the highlight of your afternoon. [Kotaku]
