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?
