This street performance is going just as planned with Darth Vader taking on a Jedi in the middle of a public square. To be frank, it doesn't seem like the Dark Lord is doing all that great, but even he can't predict what happens next.
A random dog surges from the crowd to take on the Dark Lord. The Jedi, along with the rest of the crowd including the dog's owner, just stands back and watches as "man's best friend" defeats the galaxy's most evil Sith Lord.
It's clear, Darth Vader is no match for this canine.
