Cartoon Network used to show it in their Adult Swim time slot, but since it's only 6 episodes, they don't show it very often.  I got Vol. 1 (#1/2) and Vol. 2 (#3/4) from Fry's, and Vol. 3 is on its way.  If you look carefully, the fight scene at school in Episode #3 has what looks like a dead Kenny from South Park flying in the air.

Sypnosis: A young boy lives with his small time trash journalist dad and his grandfather.  The town has a large factory that shapes like a cloth iron that releases steam.  His older brother is a baseball player who went to US.  His brother's high school age girlfriend is making a move on him, a strange gal on a scooter arrived who beats his head with her bass guitar.  Strange things like a robot and cat's ears are coming out of his head.  What makes it so appealing to me is that aside from the usual pubescent sexual anxiety, confusion and jealousy, there's a strong Freudian subtext underneath all this (symbolism, Oedipus Complex)

And the eyebrows.  Watch the creator's commentary on DVD about the eyebrows.  It's pretty funny.
