When I was young I tried coming up with elaborate schemes because I never wanted to do homework, realizing now if I had just done the damn homework it would've taken far less effort to do than my schemes did, lol.

That said, I still hate homework.

When I was younger I used to pronounce yellow as wellow.

In grade school up through middle school, I would play with my color pencils a lot as if they were Star Wars characters in a lightsaber battle. Again, I never liked doing homework. ^_^

I used to write 'was' as 'wos' even though I knew the correct spelling had an 'a'. It sounded like it should've had an 'o' in it and therefore became a matter of principle.

When I was about 6-7 I got my mums talcum powder in the middle of the night, mixed it with water, poured it all over the living room carpet. later in the morning my mum threw a shitstorm at the mess I made. My only response was "but i wanted to play with my cars in the snow"

In primary 5, shot the head teacher in the ass with my friends homemade bow and arrow in front of the school in the gym hall.

In high school, after doing my work and finishing it, I'd draw little stickman martial arts fights at the corners and sides of my books and create little flickerbook fights. I'd occasionally hear some of my teachers laughing while they marked my work.

Not really a stupid thing but I kinda felt stupid at the time, I had a strange habit of hitting on girls not knowing they were actually lesbians (they honestly didn't seem gay or anything). I eventually found out that 2 of those girls were actually seeing each other, didn't really stop my interest in them though ^^

Not me but one of my brothers. He climbed up the piping of a 4 floored derelict building, got to the roof - then fell through it, fell through the attic, the 4th floor, 3rd floor and claimed to have landed on his feet on the 2nd floor. We found him laughing his ass off.
