Dude...That totally caught me off guard.
The first moo, I kinda chuckled cause I thought it was pretty cute, then came the other stuff, and I just couldn't stop laughing.
Sure, the art wasn't all too good, since there was just a few bits of green squigglies for the grass.
Animation wasn't too good either, considering only their faces moved but what it lacks, it makes up for in being pure funny. 7/10 seems fair, so let's go with that.
