My friend Jeff, a former co-worker, sent me a link to INDEXED, a blog by Jessica Hagy. She uses charts, graphs and Venn diagrams to explain her observations.
Also a few jokes from his seven year old niece:
Q: What has a broom and flies?</p> A: A jelly covered janitor!
Q: What is green, fuzzy, has four legs, and if it lands on you it will kill you?
A: A pool table!
