Hahaha the popcorn helmet and hat on the dog is a great visual gag. The length of the video works great so it keeps it punch, and the intro is pretty catchy (would be catchier with some background music accompanying the vocals). My suggestion would be to add some background music, not just during the intro, but throughout the rest of the video, as that will give it a boost (and cover some of the hiss in audio). Fun stuff though, very creative!
