My favorite of the two is I'm with Stupid as i've seen it an uncountable number of times and it never gets dull. The same lines that i thought were hilarious the first time i saw are still hilarious to me now. As in many of the Spongebob episodes through season 3, there are hilarious one-liners and good natured humor aimed not only at kids but adults as well. Procrastination is not a personal favorite of mine but that doesn't mean it was bad(definitely not!). It was a funny look at Spongebob's personality and it showed how Spongebob had more depth than the average children's show. Plus it was definitely well thought out(not something i can say about the latest crop of lazy writers for Nickelodeon shows).
A great episode.
