Duty and doodie are not the same thing.  But it would be funny if they were.

But we can have some fun with this. 

• There are six special kinds of duty.  How many special kinds of doodie are there?  (Beer poops, etc.)
• Everyone has a duty of reasonable care.  Do people have doodie that is seasonably rare?  (I don't even know what that means.)
• Doctors have special duties.  They also have special doodies.
