What is the prize? 
Umm...

Well, I'm sure you'll remind everybody that I drank the prize last time (in expectation of winning like)....

So perhaps it would be better not to promise anything I can't deliver...

Or... okay then, I'll send a DVD (of my choice) to the winner via Amazon if you give me your address like... how would that be...? Couldn't be fairer than that like...?
