These guys, Ryan Higa and Sean Fujiyoshi, are the the #1 subscribed comedians on Youtube and get even more hits than KevJumba does.  I just saw a few of their vids, some of which have 6+ million views. They are hilarious in a super goofy way… though some gimmicks end up appearing in multiple clips.

I’m not really sure what their target demographic is, but here is one of their clips ’how to be a nerd’
