You give a man color film, and sooner or later you will catch him out in the garden taking pictures of flowers. This seems inevitable. He just can't resist. He's got this colorful film, y'see, and he spies this colorful flower, and...well, not being a chimp, he does realize that there are enough flower pictures in the world already, and that the one he's about to take isn't going to be of any use to anybody. But he can't help himself. It's too great a temptation to resist. He succumbs to the weakness.
