Sometimes, the best attribute you can hope for in a TV newscaster is the ability to avoid annoying the viewers. ABC 15's Steve Irvin has that down pat. Three channels down, you'll find a mustache with an ego. Two channels before that, a bit of a doofus. Irvin, who's been at ABC 15 for more than a decade, keeps things pretty neutral without being boring. Like many anchors, Irvin has a signature look, too. including raised eyebrows and a slightly higher tone of voice that says, "This is surprising stuff, people." It actually works (on us, at least).
