Are caterpillars good to eat?
Johnny: Daddy, are caterpillars good to eat?

Father: Have I not told you never to mention such things during meals!

Mother: Why did you say that, Junior? Why did you ask the question?

Johnny: It's because I saw one on daddy's lettuce, but now it's gone.

An Unusual Vet
There was once an aspiring veterinarian who put himself through veterinary school working nights as a taxidermist.
Upon graduation, he decided he could combine his two vocations to better serve the needs of his patients and their owners, while doubling his practice and, therefore, his income.

He opened his own offices with a shingle on the door saying, "Dr. Jones, Veterinary Medicine and Taxidermy -- Either way, you get your dog back!"
