Have you ever taken something apart, only to realize you have NO freaking idea how to put it back together?

I picked up one of those small gumball machines at a garage sale…actually, I think the lady shoved it into my hands and said, “Take it!” So I did. It needed to be cleaned which meant I needed to take it apart. I could see, obviously, that the first thing to do was unscrew the screw on the top. So I did. And the bottom fell out! But that was OK. It was just one big piece. Then I pulled the globe off and unscrewed a little bolt that I still have NO idea what its purpose is, then took out 3 more round plastic pieces, but I didn’t pay attention to what order I pulled them out or how they sat in there… sigh I know better than that, but I just didn’t think it could be that hard to put back together! After I got it all cleaned it up, it took me a good 30 minutes to put the stupid thing back together! But I did, and it works and it looks right so must be right, right?

You ever, say, pull a car engine apart? You ever have pieces left over, lying about in the driveway after you put it back together? : )
