Yes, it's short, but I don't think most people get the joke. Did anybody notice the title? "The Greatest Flash Movie Ever"?
Nice. The guy just moves in an endless loop.
Now, don't be fooled-
It's a one-liner, and if I were forced to: A.) watch this movie forever, or B.) Have squirrels gnaw my testicles until Brittany Spears becomes a talented actress, I'd go with the testicle thing.
I chuckled. That's all it will ever get from me, and I think that that's all the author was going for.
