Simple Pleasures

What are some of the insignificant little things that always seem to put a smile on your face? Things that aren't necessarily obvious, or explainable, but just cheer you up ever so slightly?

I'll start, with one from right here in the forums:

A little less than two years ago some dude announced in a thread that he was having a "dood morning," and I just couldn't let it pass without making a smartass comment or six. One of my Brothers In Smartassery from Ohioi picked it up, and now the accepted spelling of dude is dood. 

Why do I still get a smile every time I see the word Dood? I dunno; it's just funny to me. Simple pleasures for simple minds, I suppose. What are your simple pleasures?
