I politely ask for the SaNdWiCh, and then while the sandwich holder is confused by my capitalization (which is apparently worthy of debate), I take the sandwich and replace it with a rock, and, as we have learned from greek mythology, these can be eaten and easily confused with babies, allow the current sandwich holder to eat the rock believing it is the sandwich. I then take the sandwich and hide it in cave, which as we also learned from greek mythology is a great place to hide things until they mature. What does a mature sandwich look like? idk, moldy probably.
