From a too-fancy party last night: "Guess what, Bird Dog, I have an announcement for ya."
"OK, I am listening."
"I've gone vegetarian."
"That's cool," I said. "You are fitting in exactly to the joke about vegetarians telling everybody. But why?"
"Mostly to feel morally superior to other people like you, secondarily for my triglycerides."
Excellent response. I love our friends. So lucky to have them all, especially at Christmastime. I didn't bother correcting him on his medical ignorance, because cheerful friends don't correct people at Christmas parties.
Nobody likes a pedantic a-hole.
