During a conversation about the weather in work, I happened to mention that
when it rains, one of my cats has a habit of bringing frogs in, which then
take refuge in their water dish. Someone remarked that they didn't like
frogs because her Grandfather would stick his fork through them if he found
them in his greenhouse. I said what a shame, think of all the good they
could do [thinking of them eating unwanted bugs]. The general opinion was
that you *don't* want frogs in your greenhouse, but no one knew why.

So, why not?
