The problem with the whole thing, aside from the dumb questions, is that they only alotted him three minutes of live air time, but he spent half that time on the opening and closing remarks. Was kind of a waste in that regard.
Think what they should have done was make this a special instead of tacking it onto the end of an episode(which also suffered since it lost a few minutes of story time). The first 15 minutes of the special could've been a short with the family similar to that Maggie daycare one, then give Homer the last 15 minutes to do his live thing.
