Awhile ago,
thespianmobile& I played a new game -- The Stinkiest Sandwich. What is the stinkinest sandwich you can imagine? Rule: it has to be made of actual foodstuffs, things that (reasonable) people eat. No poo & dead skunk sandwiches allowed.
IIRC, our sandwich consisted of:
Rye bread
Durian fruit
Asofoteda
Limburger cheese
The Leftover Fish that your Coworker Microwaves in the Breakroom
We were pleased.
