Science or Sorcery?

You slap some meat on a couple slices of bread. Maybe some lettuce, tomato, a gherkin or two or more. You two hand it and raise it to your mouth and insert. Close the choppers and you have your first bite. Good so far until the bread gets compressed and stuck to the roof of your mouth. You try to pry it off with your tongue. You try creating some downward suction to release the goods. Sometimes only a finger scraping at the ceiling will loosen the prize. Once in a while panic engulfs you when your failed attempts amass to a number greater than you care to know, and you begin to choke or lose your breath or gag.

Is there a solution my momma never taught me or is it a common battle amongst man? Is this a fault in the design of the mouth or of the sandwich? Is it God or demon? Science or sorcery? Stroehmann or Wonder?
