How many beers deep do you have to be to let your buddy punch you right in the fuckin face?

Seriously. How many beers deep do you have to be to let your buddy punch you right in the fuckin face? I see videos like these all the time and I don't get what the dude getting knocked the fuck out gets out of it.  Like no way this can turn good.  Chicks don't want to bang dudes at parties with golf ball size lumps on their heads and have the title of getting "one punched" all night. On the flip side, the dude in the red shirt that knocked this kid out has a one night pass to all the pussy he wants. Just make sure in this equation you are that guy.

Oh, I belive that sound you heard was "one punched" getting his head rocked off a keg on the way to the ground.
