The one kid in the second video looked like Fonzie. Is Fonzie emo now?

You mean the guy in the brown leather jacket @ 1 minute in? Nah, he's with the punks. Story goes the punks are pissed at the emo kids for biting their style, that guy is just latching on to the shitty punk kids in the spirit of the lynch mob - despite being on a whole other level of elvis meets the Fonz fuck awesome.
I also love how they say emo, "ehmos, ehmos, ehmos!"
