A "Glossary of Gestures for Critical Discussion" pokes fun at us academics, who merely try to spice up a lecture and keep students engaged. My favorite is the "Italian waiter: Use when making a cultural observation."
If you're inclined, you can order rulers or coasters with the gestures.
At least the gestures answer Will Farrell's question in the movie Talledega Nights: "What do I do with my hands?"
- Watch you professors during the next class: how many can you identify?
- What other gestures do your professors use?
- Do you notice a difference in how business and other faculty use gestures?
