A bag of dry dog food works pretty well. Hey, it's for emergencies, right?! When I was a scout leader we used to suggest dog bones for emergency food. Anything else was always eaten by the scouts on a routine basis, leaving nothing left for emergencies. Those dog bones were always still there, ready, waiting and available though...
When my youngest brother was in HS the rage was for them to eat Milk Bones as a snack.
I don't know if it was to try and gross people out or because they actually liked them. Maybe both.
