Action

After I explained that petals weren't reproductive, the crazy woman in the back of the classroom (there's always at least one, but this was my first year teaching and I didn't realize it), blurted out, "so petals are basically the makeup and perfume?"
Somehow I couldn't resist replying, "Yes, if the makeup and perfume attract the guy driving the sperm delivery truck, and he is a member of an entirely different kingdom of organisms."
Plant sex, with its animal intermediaries, just doesn't have any analogous practices among humans.
Many of these were taken on a cool day in Idaho.  You just never know when you are going to find the action.
