Quote from Daphne in Four for the Seesaw
Roz: Frasier, are you really afraid of needles? Frasier: Oh, not really, no. I just say that to encourage people that really are. Roz: Well, they can use the help. You know, those needles they use are about this long and if it hits a nerve when it's going into the muscle. Daphne: Shots are perfectly harmless. You've got nothing to worry about. Oh, sure, you hear the occasional story about somebody getting an air bubble in their vein or the needle getting stuck in a bone and the tip breaking off, but that's the exception.
