That's the spirit! And while you're at it, take her out to a steak house (cholesterol) or order a big fat tuna steak (mercury) and have her get you a box of cigars (global warming and smoking)... perhaps you can end the evening using hair spray (ozone depletion).... Unfortunately, I couldn't think of anything romantic about DDT, but if you can work that into your romantic evening, by all means, do so!
P.S. I have a sneaking suspicion that florists all across the country are going to be inundated with extra orders for roses this year.
