This is a bad lip-reading of NFL players and coaches. Basically they took the sound out of the original videos and produced their own interpretation of what these players and coaches were saying. This is a parody because it mocks the NFL. It makes them look really stupid. NFL players are worshiped in this country. I'm not a huge football fan but I'd still be scared to get into a bar fight with them. Even the quarterbacks because I'm pretty sure the NFL escorts them in the off season. They are thought to be strong and tough and manly, but in this video they are quite the opposite. They sound very dumb/ immature/ childish in this video. Every comment that is made in the video either doesn't make sense (but is still hilarious) or it is completely ridiculous (often times both). I think that besides the dialogue there are two huge contributing factors to making this as funny as it is. The first would be the choice of voices. My personal favorites are those of the beloved Vikings running back, Adrian Peterson (0:10) and this other guy (1:22). Pure genus. Lastly the realism is almost unreal. On many occasions, the lip reading is identical to the lips (0:29). And we can almost let ourselves be convinced that some where coach Harbaugh is out there yelling about how he wants cake now.
