1. Fly a kite.
So fun, good times. The kiddos love it, and so will you.
2. Eat a bagel.
They taste good and will temporarily give you something to focus on besides your crushing boredom.
3. Do a backflip.
It doesn't matter if you know how to do one or not. Just believe in yourself and go for it!! That should probably maybe work, but if it doesn't, that's not my fault so you can't sue me (you did it on your own free will, okay!).
4. Be Steve Urkel for a day.
Your family and friends will just love it when you strut around all day in some kooky suspenders and comically large nerd glasses repeating "Did I do that?" like a broken record. FUN!
5. Dig a hole.
I once watched part of the extremely influential film, Holes, and was instantly inspired to dig a few holes of my own (my mom wasn't happy, but I guess she just doesn't understand art). Hole digging is truly a great way to spend your time.
6. Build a log cabin.
Not Lincoln logs, those are for babies! I mean an actual log cabin like the one Honest Abe lived in; like the one on the maple syrup bottles. I'm sure it'll occupy you for at least a few days.
7. Break a leg.
I mean this literally; break your leg. The physical therapy and healing process will give you a thrilling new way to pass the time and challenge yourself in a whole new way.
8. Make your own beer.
One day in my 9th-grade science class, we made our own beer with yeast and fermentation and stuff. The only downside to drinking the stuff is that you'll go blind, but that's the only drawback.
9. Stare unblinkingly at a stranger
It's a really exciting pastime because you either end up making a friend or running for your life (which in my experience, has always been a great form of involuntary exercise). Whether they like you looking at them or not, you're gonna do it, and everything will be great (especially if you try this one in densely populated urban areas, like Manhattan)!
10. Fake your own death.
Now, this one's a classic! Truly a fun and creative prank for people of all ages, your loved ones will scream for and cry tears of joy after you explain that your elaborate scheme faking your own death was just a little joke, all in good fun. I'm sure they'll be understanding.
