What is the dumbest thing you've done as a kid?

One time a while ago I went to the pool with my sister and parents, and I was walking by the pool, then I slipped and fell in, but instead of kicking and screaming trying to get up, I literally just layed there and slowly sunk to the bottom. My Dad pulled me out eventually though. Apparently I thought I was just going to float out or something lol

I stuck a bunch of stuff up my nose and had to get it removed.

i ate clay lol

i ate lego

We went to bunnings once we left the rabbits in a cage outside. The dogs were outside. AND RABBITS CAN DIG!! We came back to my rabbits head on my ground. Believing my parents I thought it was a teddy. This isn't really one but its all I can think of-_-
