Hey, does anyone have good short poems?

These aren't for homework, I just like reading them. I even make a few of my own. "This is my first poem, It is pretty strange. The best thing about it, is that it won't change." "It's hard to make one, I'm trying to now, How should I end this... With a big pow?" It's so hard... >:/ Oh, and would these clify as long couplets?
