Dr. Patrick Moore was defending the pesticide manufacturers he represents, but wouldn't put his poison where his mouth is.

Extrait : Bientôt dans vos assiettes... - Interview de Patrick Moore

This is one of the best foot-in-mouth moments I've seen in a long time. Dr. Patrick Moore, a paid spokesperson for the nuclear, logging, and genetic engineering industries, was being interviewed about glyphosate (aka Roundup), a pesticide produced by his client, Monsanto. Recently, an international group of cancer experts claimed that glyphosate causes cancer. Dr. Moore disagreed, saying, "You can drink a whole quart of it and it won't hurt you." But when the interviewer offered him a cup, he refused and walked off the set with a final, "You're a complete jerk."
