Nerds, geeks, word nuts, and plant lovers: What's your best flower joke?

I’m studying flower sex at the moment, and it’s got me thinking. Almost everyone—some more than others—has a few human sex- related jokes to tell. Somehow, that should make a flower sex joke even more funny. And so many of the flower part names have more than one meaning or are extremely similar to other words—style, stigma, pistil, filament, ovary, receptacle, whorl. Surely there is a geeky-hilarious, word play joke in there somewhere? Someone please enlighten me.
