Fishing for Fur
You are sitting at your tying bench when suddenly you realize that you need some squirrel hair to complete the fly you are tying. You might want to head down to your local park for some "squirrel fishing". All you need is a string and a peanut and you are in business. How you manage to get the squirrels you catch to give up some fur is your problem.
Editor's note: The scary thing is that the site I found this mentioned on is: http://www.eecs.harvard.edu/~yaz/en/squirrel_fishing.html
I am glad to see that those liberal arts educations are being put to good use.
