This has always been one of my favorite episodes of the Dick Van Dyke show. It mixes such funny situational humor with something really beautiful. It's one of the best "Laura" episodes, if you want to call it that, because it gives her a time to show the real depth of her character. And the poem at the end, it always gets me:
Mine eyes will ne're behold
which my heart dost see so clearly
inward stirs this passion, deep
beknighting, leading my path away from all
and to my love
I reach out for thee
and pray your hand be there to welcome mine
your light to illum where
my light be spent
for my soul is sore
