Heh, the memories
When in 4th grade, I figured the best way to impress the girls was to be a good skateboarder. So I bought a wooden board (state-of-the-art back in the late 70s) and skated my ass off. I got pretty good, but the problem was that there weren't any girls at the good skateboarding places, and if there were, they wouldn't have cared anyhow.
Then in 5th grade, Rubiks cube came out. Well, I saved up and bought one of the originals and learned it till I could solve the top 2 layers in under a minute (not hard to do). I was stumped on the bottom layer, so I bought a book and memorized the moves for that layer. I could solve the whole thing in under 2 minutes. I brought the cube to school, thinking that I would be a total "chick-magnet" with my 1337 skills. So at lunch, I whipped out my cube and to an amazed crowd, I solved it in about 2 minutes. Then some jerk-off borrowed the cube after I scrambled it, he popped off a side piece, disassembled and then correctly reassembled it. That was apparently more impressive to the 5th grade girls, so he got all the chicks! Heh, not really, but more folks were impressed with his trick than mine.
By 6th grade, I decided that learning to juggle lunch milk cartons was my ticket to the lady's hearts. I got pretty good at juggling, but still the girls weren't impressed. I think 7th grade was magic tricks, and 8th grade was... well, it was playing D&D, but I had given up on impressing the girls with my 1337 skills at that point.
It was probably around 10th grade that I realized the best "trick" to impress the ladies was to be myself and make them smile. It's a lot less work, too!
