20 things i've never done

This is not one of those "list of things to do before I die" type of things, because some of the stuff below I have no interest in doing; see if you can guess which.

1. Water-skied
2. Gone bungee jumping
3. Watched Wayne's World in its entirety (I've only seen clips)
4. Learned a polka song
5. Used rollerblades (roller skates, yes, rollerblades, no)
6. Piloted an aircraft of any kind
7. Ridden a unicycle
8. Played a ukulele
9. Read War & Peace
10. Owned a house
11. Visited anywhere outside of the United States
12. Learned how to say "Where is the bathroom?" in 5 different languages
13. Ridden a motorcycle
14. Went camping (to the best of my knowledge, I've never done it)
15. Bought a comic book
16. Wrote a feature-length screenplay
17. Gone skydiving
18. Rode on a public bus
19. Dated a scientist
20. Drank whiskey

I actually had to really think hard to come up with 20 things I've never done that weren't outright ridiculous.
