At a convention of biological
scientists, one prominent researcher remarked to another, "Did you know
that in our lab we have switched from mice to lawyers for our
experiments?"
"Really?" the other researcher replied. "Why did you switch?"
"Well, for three reasons. First we found that lawyers are far more
plentiful. Second, the lab assistants don't get so attached to them.
And third, there are some things even a rat won't do
."
