I saw that too last night ... I'll check if that episode is on the DVD's.

Speaking of DVD's, for anyone who has these or the Simpsons DVD's, there are commentaries -- but they have them in a terribly unintuitive place. If you look under the Languages menu, there is a commentary language. They're hilarious on both sets of DVD's, but particularly the Futurama ones, because the writers/producers/etc are all techie's, so they point out some really clever stuff.

Not to mention the guy who does Bender is on there a lot (along with the guy who does Fry, and others), and he cracks me up ...
