Absolute crickets, but I am thinking about the tincture episode. But I think in that one he goes to the home to talk to him. And he he - I mean Homer, and him is grandpa. Not the other way around. I have no idea what this is.
I cheated on this one because I scrolled down. It was funny because I don't think I watched this one too much but I did catch my gal watching it recently (she never watched The Simpsons, so she went through a whole thing where she watched all of them when we had a Disney trial.) Something I hadn't noticed about this episode as a kid was "big egg!" It also shows how rough an unpopular decision can be =P!
p.s. - I think the best joke in the whole episode is the rock of triumph or whatever it's called. Exuberance, something like that.
