Do you like contests?

Do you like contests?  I’m betting most people would answer yes.  Even if I know I have no chance of winning or would prefer I not win (which would be wierd), my competitive spirit keeps me coming back for more.  In the realm of the internet and blogging I’ve seen lots of different contests: photo contests, writing contests, guessing game contests, comment contests, etc and I’m sure there’s a million others out there I haven’t heard of or seen before.

So my question to you is: What is the best contest you have ever entered and why?
