I thought I'd throw this out, given that my idea failed, not completely sure why, thought maybe I could get some constructive criticism. Be gentle 
I wake up Saturday morning, and bring up Drudge Report. They're reporting that Paris Hilton is going to jail. I immediately remember those "Free Winona" t-shirts that got sold after Winona Ryder got caught shoplifting, so I swing into action.
I come up with a simplistic "Free Paris" design, and put it on six different t-shirts on cafepress. You can view them here for reference. I did it in about five-ten minutes while eating breakfast.
I then jumped on Adwords and put together a really simple campaign to promote the CafePress store. I chose these keywords and bid $.35.

Support the unruly heiress with a
hilarious t-shirt - "Free Paris"!
So anyhow, long story short, blew through $20 without a single sale.
Hope somebody can point out my blatant mistakes so I can be more profitable next time.
