I'm not dumb, but I can be stupid from time to time...

• When I was 7, I went to the snow in the mountains behind Hobart. I was so enamoured that I put some snow in a bottle in order to take it back to my school for show and tell. I was devastated when it melted.
• When I was 12, I went to an acting troupe with my friend Daniel. We sat in a circle and had to say who our favourite actor was, and why. I said "Tom Cruise, and because he's Australian." Everybody looked at me funny and the teacher said, "I don't think Tom Cruise is Australian." I got flustered and said in reaction, "Oh, yeah, well, you know what I mean!" I never went back.
• When I was 20, we had a New Year's party at our house on Hanworth St. At about 5 in the afternoon, I decided I wanted chips, and that I wanted to deep fry them. So, I emptied the remnants of our oil into a saucepan and put it on the stove. I kept checking it every ten minutes or so, but it wouldn't boil, so I couldn't figure out what was going on. The next time I went to check it, it was on fire. Daniel rushed in at that point (having just gotten home from work) and threw the fireblanket on it. The fireblanket then caught on fire, so the extinguisher came out and our freshly cleaned kitchen got doused in white powder - which I then had to clean up.
• When I was 21, I put some water on to boil and then went and talked to my cousin on the internet for ages. Smelling something burning, I came back and found that all of the water had evaporated and the bottom of the saucepan was burned. Cursing, I turned off the heat and put the saucepan on the bench - which to this day still has a massive heat ring from where it was warped. We'd only been living in that house a few months. I was thusly banned from the kitchen.
