This is some vintage video of an old match between Triple H and Stone Cold Steve Austin. Stone Cold finishes Triple H with a stunner, and a crazed German fan runs into the ring and attacks Stone Cold. But before the fan could do any damage, Triple H drops the attacker with a real Suplex, and the match referee jumps in to help with some vicious foot stomps.
I guess this fan found out the hard way that wrestling is definitely real.
