h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Ok, I've come up with some really odd uses for a towel, since its the only thing I know of more useful than a good knife.
1. Hand held catapult.
2. Impromptu shield.
3. Cover for the pipe you want people to think is a gun, so they'll leave you alone.
4. A cheap throw rug.
5. Target for your arrows, when you spend 60,000 dollars on a new bow.
6. Excuse to get out of seeing a bad movie. For example: "Sorry, You see, there was this idiot who brought a towel in, and he wouldn't quit blocking the projectors......"
7. Quickway of disarming a person of a knife. Example: "What the heck, you really intend to fight me with a towel?" Followed by: "Where the heck did my knife go? Oh, uhh, you have it now...."
8. Silencer for your lead pipe, when you just have to whack something, but don't want to make it obvious.

9. Quick cover for that shipment of weapons grade plutonium you stole from Lybian terrorists.
10. Emergency coat, in case of rain.
11. Good fire starter, when you've ran out of twigs.
12. A dog leash, or piece of rope.
13. A snapping weapon, that like a whip, can be used to scare the crap out of people.
14. Impromtu bath robe.
15. Handy means of embarassing your friends. (Show other people their towels....)
16. Cover for whatever the heck sort of interesting rocks you've picke up, instead of slaying the rabbit for its fur....

Considering #9 you sound like a Back to the Future fan. Good on you.
