Chicken Pot Pie Bumper Sticker. My 3 Favorite Things.  11" X 3" size.

For many, this sticker will carry a subtle reference to Marijuana.  Cannabis. Getting high. 

Pot is a common term for Cannabis.  See extra scan for clarity on this reference.  (Only the bumper sticker is being sold here.)

But, of course, Chicken Pot Pie is also a common cooked food and some will not get the reference to 3 things.  So one can be somewhat incognito while still communicating with those who get it.
