the goblin is John Goblikon and he even has his own youtube talkshow. they're rad, never take themselves too seriously, but they're super clean and skilled. Should check out "we need a gimmick" and "no one survives" both pretty awesome videos, and super catchy songs.
No, that's a real goblin. His name is John Goblikon. They can't seem to get rid of the creature, so they tolerate him (and his miserable talk-show). That's being said, I recommend you react to their music video 'Dressed as Goblins' off their new album!
Pogs! Pogs were a flat cardboard disks which you stacked a bunch of them, then used a metal pog to slam it into the stack -- that's as far as I got into playing the game. Lol, was a 90's thing. xD As for the lyrics! I do not know this as a fact, but to me, it seems like they are written in a style as if the singer was a goblin. Thus, the oddities in the lyrics; especially the bit about taking a bath. lol
