I love Jack Handey's "Ideas for Paintings." I heard this on the radio when I was out somewhere in the middle of my long drive. I remembered it tonight as I was reading this humor test -- reading it aloud for someone who was trying to answer the questions and when I got to question 10 -- "Which of the following 'Deep Thoughts' by Jack Handey is the funniest to you?" -- it took me about 10 tries before I could get the second "Deep Thought" out without breaking down into hysteria. And the second one wasn't even the funniest one. I haven't laughed that hard in years.
(Thanks to Diane Meyer for the link to the test.)
