In Street Fighter's famous bonus stage, the goal is to smash cars. That's the same goal in Super Street Fighter IV: Arcade Edition Ver. 2012—even if it looks like the goal of SF character is something else entirely.

The glitch appears to happen after Ryu unleashes a shoryuken on the car.

Even when time runs out, Ryu just keeps going and going and going...

This was a bug discovered by a Japanese gamer while playing the title at the arcade, and it was posted to YouTube as a warning to those players who use the character.

As Kotaku commenter lgboix pointed out, Street Fighter saw a simliar bug in the Street Fighter II: Championship Edition—minus the humping.
