STRANGER THEN A TWO HEADED TURKEY

Stranger then a two headed Turkey.

When you meet someone that is totally of the rails bat shit crazy but doesn't know it.
When you just give that look a turkey gives When trying to figure out what that crazy person is trying to say so you immediately smile and nod your head acting like you understand so they go away.

David was stranger then a two headed turkey with all his talk of ufo sightings and Aliens stealing his trash cans.
