You never know when you might need one...

My wife was complaining this year that every time I went out to the garden I would return with arms full of courgettes. So we've had courgettes with pretty much every meal for the past three months, and she's sick of 'em. But now I can tell her that they have many more uses than simply as a foodstuff. You can use them to battle off bears! See? I would hesitate to make claims that are too grandiose, but we haven't seen any bears around here lately, so they must be working.
