I asked my doctor the other day if I could get a full body transplant. He said dryly, "You're not a candidate." At least he thinks wearing masks are a joke.
My dermatologist has a sense of humor. A few years ago, I had an insect bite on my leg that become an infected lump. As he was preparing to freeze it off with liquid nitrogen. I asked him, “Doctor is this going to hurt”? He responded, “I won’t feel a thing”.
