"Why Have Scientists Begun To Use Lawyers Instead" joke

Why have scientists begun to use lawyers instead of lab rats for research?
Two reasons: first, they are more plentiful than rats, second, the researchers don’t get as attached to them.

One problem, though, is that no one has been able to extrapolate the test results to human beings.

Response:

C’mon Guys! That’s only half the joke about researchers, lab rats and lawyers. There are four, well-known reasons why researchers prefer lawyers to rats:

1. Lawyers are more plentiful. (You got this one.)

2. They are easier to train.

3. Researchers don’t get attached to them. (You got this one, too.)

4. There are some things a rat won’t do.
