Geek ear

So I'm eating dinner and half-heartedly watching junk TiVo recorded, including this episode of Landscaper's Challenge (in case you're wondering, it's a homeowner thing), and I'm not actually watching but listening kind of and I hear the client make some jokes and I know that I know that voice from somewhere. I start watching it intently and racking my brain for a few minutes. Where have I heard that before? Books on tape? Narrator in a car commercial? Cartoon voice? And then it hits me: I've heard this guy "Al" dozens of times, but I've never seen him before. He does the commentary tracks on all the Simpson's DVDs.

It was show writer/director Al Jean getting his backyard done.
