Alright, here's one of the many:
When I was a kid, I went to a school that had other kids grades 1-8 (ages 6-13ish) in the same school.
When I was 6 and going into first grade, duke nukem 3D had first came out, and I thought he was AWESOME. So, I would go around saying some of the things he said to be as awesome as him (trust me, the logic CPU in my head wasn't running until later in my life).
This one time, I was on the bus, there was this annoying 7th grade girl and her two friends who would constantly annoy me. So this one day (I swear it gets funny), I remember it clearly:
She asked me if I was gay. I said no, of course. She was like "Y NOT, IT MEANS HAPPY LOL" and I was like "I'm not happy."
She was like "Why aren't you happy~~?" and her friends were like "YEAH, WHY AREN'T YOU HAPPY, HAHAHA"
And I was like "because I have to sit next to you."
And she was like "...take it back you little scumbag" and her friends were like "ooo, he said he doesn't like you~"
And so after she called me a scumbag I was like "You're an inspiration for birth control." (- Duke Nukem) and, at that point, I didn't really know what it meant, or how bad it meant. I just felt like saying it? I figured it was something bad because Duke says it when he sees the alien queen, but I didn't know how bad it really was at the time.
So her friends burst out laughing, and then I got the shit kicked out of me.
It hurt at the time but looking back at it, it was pretty funny.
