Urine. Cigarette butt. Salted coffee. Chunks of paper and alu-foil. All kinds of chemicals one can find in a printing industry. Moldy bread. Acrylic resin. Eraser rubber.
Spider, once. Swallowed.
Once I shaved myself using bug spray instead of foam.
Oh, and if you eat enough dog cookies on a party, your hair will be shiny next morning.
Oh, salted coffee! Long ago, when I worked at a fast food restaurant, that was a popular prank for the employees to play on each other.
I was on my first trip to Egypt a few months after our wedding with my wife, who is Egyptian, and we were on a Nile luncheon cruise with her extended family and friends. It was a buffet lunch, and being an open-minded eater I tried just about everything, including a cute little potato. The potato was bite-sized so I popped the whole thing in my mouth. As soon as I bit down, I got a very intense sensation of sour, bitter, and salty, so intense that if I had been anywhere else I would have immediately spit it out. But I was around all my new in-laws and friends, and did not want to make a scene, so I chewed that thing up and swallowed it. It is the worst thing I have ever eaten.
A few minutes later I turned to my wife’s second cousin next to me and said, “Say, what were those little round things in the white bowl?”
“Oh, it was a pickled lemon. I was surprised you ate the whole thing. Normally you just take a tiny little bit as a condiment.”
I didn’t even know pickling lemons was a thing.
Was kinda chewing on the end of an ink pen one day and suddenly tasted something terrible, ink. Very bitter.
When I six I got a bb gun for Christmas, and it came with a small tube of gun oil. My gums were sore from my permanent teeth coming in, so I would chew on the tube of oil. At some point I chewed through it. It was indescribably bitter; fortunately, I was close enough to the bathroom sink where I could immediately spit it out and rinse my mouth.
