Oh! I do have one! Actually many. I took pottery for four years all through highschool, and I was a character in there. Somehow, I was very talented at pottery, but I still was a clutz and dropped, spilled, and broke things all the time. No one understood it. This is one of the most infamous stories.
This was my senior year of highschool. I was working on the basin for a waterfountain I was making. The basin was over 2 feet wide. Which is huge. I had to center around 50 pounds of clay. Because it was going to be so wide, I had to center this clay on an oversized batt (the thing you put on the wheel to through with). It was larger then the splash pan, so I had to remove it. The sheer volume of water needed for this, and my reputation for making a mess, I went to the middle of the room, and had to throw in my bathing suit. I brought it in this day to do it. That was embaressing to say the least. My teacher (an ISFJ), thought this was the funniest thing in the world. She was laughing the whole time. The class only had 9 people in there and we all knew each other very well. The class was highly interactive by nature.
Anyway. I start centering the clay. A daunting task. I was standing/kneeling to do it, which is why I had to use a bathing suit. I am centering away and things were fine. I would get the occasional "ooh la la!" out of 9, 7 were girls, and they all knew I was gay so they all poked fun. People also chucked bits of clay at me, I just retaliated. Of course getting yelled at for this (throwing clay, i.e. tossing it, was forbiddin). The clay I was using is stoneware, which has the perpencity to become gummy before going dry from not enough water. After 10 minutes of straining, I nearly had it on center. I was very close, to being done with this, and just held on. I didnt want to let go and add more water, I thought I could get it. Well it got too dry, and my hand caught (this is an electric wheel, and I locked the pedal), and it picked me up.
I got flung on my chest on top of the clay. I let out a yelp, and just yelled "ahhhhh!" I span around several times. All the while everyone in the room screamed. I got flung off eventually and rolled on the floor into a few chairs. My teacher ran over and screamed if I was ok. I sort of smiled/laughed and said ouch. I scrached my shoulder and pulled a muscle, but was ok. I was rather lucky. As soon as everyone saw me laughing, the entire room erupted in laughter. My teacher then went from concern to "Pieter! You could have ripped your arms off! How DARE you make a mess like this and take a spin on the wheel!" She was half joking with me. My teacher and I had an interesting relationship, we play-yelled at each other all the time. The antics never ended. Several girls in the class were laughing so hard they had to leave the room. Apparently I looked like something out of a movie when I did that. I NEVER lived that one down, and word got around slowly. In hindsight it was pretty damn hilarious. Although I am very lucky.
