Lawyers and Rats  
LAWYER JOKE #6

“The National Institutes of Health announced it will no longer use rats for medical experimentation.  In their place, the NIH will use lawyers.
The NIH gave three reasons for this decision:
1.  There are now more attorneys than there are rats.
2.  The medical researchers don’t become as emotionally attached to the attorneys as they did to the rats.
3.  No matter how hard you try, there are some things that rats won’t do.”
