What is the most random/outlandish lead source you've ever used?

[Justin Phillips]

Agent, Lenders, Flippers, Contractors, anyone in the business: I'd love to hear the most random way you've ever gotten, 
and subsequently closed a lead. 
We've been playing around with some more fun/niche marketing lately, and it has me wondering about some of you all's stories! We bought a redirect domain, and have been having some fun using it on billboards. We've also done some random very low cost, with potential reward things like paying for flyer-space under a local diner's glass tables. 

Marketing can be fun and spunky. Let's hear some of your stories!
