I don't own my own house and don't intend to in the near future so that knocks out a few things, so here are the only things I have actually done:
2. Protect your computer
5. Retouch digital photos
9. Navigate with a map and compass
16. Back up data
17. Paint a room
21. Hook up an HDTV
23. Paddle a canoe (do canoes have 1 or 2 oars? I know I can do boats with 2)
24. Fix a bike flat (I have replaced the tire tube but don't know how to patch a hole)
Here's MY top 20 list of things men should know that I haven't seen mentioned yet by other Anandtechers (admittedly I know some but not all of these):
1. Physical Self defense
2. Money Management / Investing
3. How To Run a Business
4. People skills (see #3)
5. At least 1 popular / semi popular sport
6. Basic weight training/exercise techniques
7. Cooking (that's right. I know a little but wish I knew much more)
8. Hook up a home stereo
9. Dance a little (I can't at all, have NO rhythm)
10. Knowing the law (not to the extent of a lawyer of course)
11. Set up a tent
12. Know how to filter useful/interesting info from junk (news, literature, movies, tv, music, art, people, etc)
13. Research a topic w/o using the internet
14. Write in a clear, logical, and easy to understand manner
15. Wash your own clothes (never did this til I was 18...)
16. Tie a necktie (learned this too late, and haven't done in a while so may have forgotten

)
17. Knowing one's options in life (this is vague I know, but encompasses several on my list. For instance I'm so goddamn sick of parents putting kids on conveyor belts to college and never even presenting the alternatives, or giving kids the means to find the alternatives themselves)
18. The U.S. Constitution (for those living in America)
19. How to travel
20. How to deal with stress
