1. Attention

Comedic dogs and patients who deliver toasts while handing doctors their urine samples need attention, just like Demetri.

2. Ability

Demetri finds that people with special abilities -- unicyclists, amateur midwives and people who can simultaneously laugh and pee -- are in short supply.

4. Money

Demetri finds there's more than one way to acquire wealth since it's not enough to be born with a silver spoon in your mouth -- sometimes you gotta shave a snake.

5. 2

Demetri examines the number 2 from every vantage, from the biological -- as when two women hit the lavatory to dissect a blind date -- to basic but unnoticed social cues.

6. 2, Too

Demetri returns to the number 2, shining a spotlight on Superman's duplicitous sidekick and how the shape of the number 2 conveys vital information.

7. Lines

Demetri demonstrates how adding lines to a drawing can change everything and laments the lack of pick-up line equivalents for breaking up.

8. Nature

The natural world beguiles Demetri as he expounds on the cruelty of duck hunting and Bigfoot's mysterious sexual orientation.

9. Space

Demetri finds that spaces in a sentence are just as important as word choice and learns that space travel in the future is disconcertingly simple.

10. Control

Demetri wrestles with when it's good to be in control, particularly when struggling with a piñata.
