#1 Bought an ear of sweet corn at a street festival in Iowa. Need salt, pepper, and of course, plenty of melted butter. The vender had provided a bottle of clarified liquid butter, so I put a big dab on, and took a bite. Tasted a little funny, so I took another bite. Still funny, so I looked at the bottle. Liquid hand soap.
#2 My uncle had a bottle of mint flavored mineral oil. His college roommate found it, liked it, drank the full bottle. Some time later, he had to pass gas, or so he thought.
#3 Customer is looking for a place to dash his cigerette. I offer him an empty soda can. He is reluctant, afraid that someone will drink it. No problem, the can is nearly empty, it’s my soda.
Several days later, my cousin, who had a bad habit of finishing off other’s drinks, found the can. Ghaak!, his cheeks puff out, and he makes a mad rush for the door.
