Considering this is a true one-off character, he certainly has a memorable moment:

I'm not going to sugar coat it: the rest of this episode is made up of real nobodies, and quite a few at that - it's a real "Who's who?" of "Who cares?" - but when you see this guy you can instantly recall his performance of "You Are So Beautiful", a real unique rendition from Castellaneta. This song has been covered over a dozen times, but this is the version that will always come to mind first for me.
