Cereal Killer

It's very fun, humourous and inventive...very freddiew. My nephew makes us watch all his stuff.

Here's the thing...Marvel fans...did it seem familiar to you?

Guy can't decide between chocolate junk food.
Robbery commences around him.
Guy proceeds to take everyone down before leaving with chosen junk food.

However, "Cereal Killer" was uploaded June 18, 2011. The first that the general public knew of "A Funny Thing Happened on the Way to Thor's Hammer" was July 2011.

So, was this all a coincidence, shared brains, Marvel ripping off freddiew or is there an earlier work that both were inspired by and I'm not familiar with? Are they both just setting that one scene from Pulp Fiction in a convenience store?
