Question 2: Short-Term Obsessions

This may be REALLY early to post, but it IS Monday, so here is the first question of the week. I arrived at it courtesy of my rapid and explosive obsession with joining cliques and adding codes to my blog (see below). It's bad. See all those? Just from one day. And there could be SOOOO much more. So I thought I would throw out the question. Most everyone has a vice, and although this hardly qualifies as a vice, it IS a short-term obsession which I am sure I will get over - like that odd obsession I had for twizzlers 2 years ago. Don't ask. So here is the question for you to answer:

What is/was your latest short-term obsession? Something you had to do/have/say/listen to/eat/be around/etc... for some inexplicable reason, but which you got over soon.

I expect creative, funny, and honest answers. I know, I ask so much.
