Well, yeah, Greg, he's got the art of trolling down pretty well.

But when it comes to exceptional trolls, we have an exception troll right here in Seattle, in the Fremont District (said to be the Center of the Universe). He resides under the north end of the Aurora Avenue (Highway 99) bridge.

Fremont Troll.

Whereas, I believe Goofballupagus is more THIS species of troll.

Or perhaps THIS?
