What is your best marketing technique?

[Josh Caldwell]

I am a mad scientist when it comes to marketing.  I will try anything once, and most things twice.  So let me ask all of you, what is your favorite or most creative marketing technique?

I will shart my most creative.  I made up a bunch of day glow orange stickers that say "I buy houses" and everytime I go to the grocery store, I place on sticker on the handle of my shopping cart.  I have bought two houses from those stickers so far.
