I remember that one. In particular the gag about "this space reserved for DVDs" was awful.
The one where Homer built his own battlebot wasn't at all funny either, but I'd seen it done much, much better when a friend of mine did it in a skit for an Efed, so I couldn't view it objectively.
The saving grace is when the guy on the radio says something like Homer is being held captive, and Homer says "Heh Heh...Wrong again Liberal Media"
