Bart has just realized his new coin collecting book requires specific coins be put in the slots.
Homer: "Son, all hobbies suck. But if you keep at it, you might find at the end you've managed to kill some precious time."
Later, when the book is full:
Bart: "Now, let's put it on a shelf, and never look at it again."
I tend to agree with Homer. Some hobbies seem to be devised specifically to kill time. I've never been a coin collector, but I have a few like an uncirculated 1974 silver dollar my grandfather gave me. It has occurred to me it might be fun to set aside one of each of all the new quarters and see how many came my way - but I've never started on that.
I do, however, collect my coins in a Doctor Who tin. It's one of the few collectibles in my living room, close to the door, and I fill it with all the non-quarters in my change. (Quarters go to laundry, and are kept nearby in a Disneyland ashtray).

My sister gave this one to me ages ago, and it's always been a favorite item of mine. It shows Tom Baker (the 4th Doctor for those keeping score) who was the Doctor when it hit big in the States in the late 70s, when I first saw it.

I wasn't that big of a Dr. Who fan then, but the police call box looks pretty cool, and I usually display it with the non-Baker side showing - so it could just as easily be the current Doctor now, and I'm quite a fan of both the "new" Doctor's who've been on the revival of the show lately.
So what do you do with a tin full of coins? Well, I cash them in at coinstar, and get credit on Amazon, which I usually end up using to buy Doctor Who DVDs. And the circle of collecting is complete.
Now that I think about it, there is one type of coin I do collect. I'll show you those as soon as I can get a picture taken of them.
