Many years ago, a warm summer night on Rt. 27 in Michigan, no air conditioning so all the windows are open, five people in the car.

"Ummmm, what's that smell?"
"Is that cheese I smell?"
"Damn, that smells good! Is there a cheese factory around here?"
"That's not Chedder. Is that Swiss cheese?"
"Where would there be a cheese factory around here?"
"Next grocery or deli we come to, let's stop and get some ham and Swiss sandwiches."
"I don't want a sandwich. I just want a big chunk of cheese to chew on!"

This went on for a good fifteen minutes until we realized we must be following that delicious smell down the highway.
Just then we caught up to the pickup truck hauling the manure wagon ! ! !
