5 things to do in your spare time

1. Design your superhero costume, just in case you ever get bitten by a radioactive spider or inherit enough money to become a masked vigilante.

2. Practice walking on sidewalk curbs and chalk lines, just in case you ever have to cross a fathomless chasm via a narrow and precarious bridge.

3. Learn Morse code. There are a whole bunch of ways this might come in handy, and surprisingly few of them involve such improbabilities as super villains and penguins in the park. (What would penguins do in a park, anyway? Wander around looking for fish?)

4. Practice navigating obstacle courses at full speed with your eyes closed. Next time the electricity goes out while you're in the basement, you'll be all set!

5. Learn to juggle. I'll let you come up with ways this skill could be useful. I'll bet there's at least three.

It's on my to-do list, that's for sure. You can do it, Dad can do it, therefore I should also be able to do it. Q.E.D.

Ha. If we don't go to Iceland, I can spend those two weeks practicing. :P
3) I don't know. Have you SEEN The Penguins of Madagascar? They are dangerous, especially Rico :D
I sorta had a fantasy throughout college (weird how I can say that now) that I would learn Morse Code with a friend, and, during exceptionally frustrating seminars or tutorials, we would communicate via tapping discreetly on the table. I'm such a terrible student. :P

Also: have you read this strip of XKCD?
I feel like the hot lava game pursues the same end as walking on sidewalk curbs, really, but XKCD demonstrates how many other things in life it can prepare you for.
Nah, I think everybody imagines stuff like that. At least, I did. Not that I actually ever got around to doing something about it....

Learning Morse code is also on my to-do list.

Oh yeah--my little sister and I used to play that game, until we got too big to jump on furniture anymore. The floor boards were the lava, and all our area rugs were rafts and islands and such. Much fun.
