If ignorance is bliss; then we've got some blissful son-of-a-guns running around.

Years ago I was at a science conference and had the displeasure of sitting next to an old cow professor who was ranting about hunters being so cruel. I asked her about the poor insects that had been killed so her salad would be fresh and free of bug bites. Then told her until she became autotrophic to just shutup and quit being such a hypocrite. The subject was changed and we didn't sit next to each other for the remainder of the conference.
