What heavy seven letter word...

Try this...
On your way home from work, stop at a pharmacy and purchase a rectal thermometer made by Johnson & Johnson. Be very sure to get this brand.
When you get home, lock your doors, close the blinds and take the phone off the hook so you will not be disturbed. Change into very comfortable clothing and sit in your favorite chair.
Open the package and remove the thermometer. Now, carefully place it on a table or a surface so that it will not become chipped or broken. Take out the literature and read it carefully. You will notice that in small print there is a statement....
"Every Rectal Thermometer made by Johnson & Johnson is personally tested."
