Did you catch much-loved, uber-enthusiastic California pubcaster Huell Howser on The Simpsons Sunday? Who's he? As the LAist blog says, "While we can't say that no one outside of California knows who Howser is, it's likely the cameo will only tickle locals who have seen Howser marvel over all manner of landmark, machine, or quirky Californian on his various PBS shows," seen six nights a week on KCET as well as various other broadcasts on pubTV stations in Oregon, Nevada and Tennessee (he's a Tennessee native). Also included in the blog item is a link to another, ahem, very quirky Howser tribute video, "Trippin' with Huell Howser." Heh.
