Pet grammatical peeve: do UFOs exist? Of course they do. Was it flying? Yes? Was it identified? No? Then it's a UFO.

Whenever someone asks me if I believe in UFOs, my standard response is, “I’m certain that people see airborne objects they cannot identify. I have a harder time with the idea that the objects are vehicles piloted by ETs with nothing better to do than anal probes and cattle mutilations.”
