The other sight gag I liked was seeing the woman who was "so perfect" for Davy tower over him by at least a foot!  I think they were really quite restrained at not using the whole height thing for comedy.  If it had been overdone, it wouldn't have been as funny, but they used it sparingly so in instances like this, it worked.

Once in a great while I hear "New Girl in School" on the radio and it always makes me think of this episode.

You're right about this episode being consistant from start to finish with the plot.  Over all, an enjoyable, light-hearted episode!

P.S. I have to admit I'm not sure whether I'm looking most forward to seeing your review of my favorite episode, or least favorite one!
