Yeah. I never put too much trust into that site. It depends a lot on regular people sending in the information instead of researching to see if the credits are real or not, which leads to the wrong actor being credited for a role, or in some cases shows that were completely made up (somewhere on that site is an entry for a show called "The Muppets Celebrate Richard Hunt." Now while I'll admit that's a nice sentiment and there are probably people who wish that had been done, it's more than a possibility that that particular show doesn't exist).
