Don't need Blue Devil and I don't know if this story would count since it involves messing with someone's mind, but figured I'd share:
I was at Target Saturday morning and saw a young boy who was clutching tightly a SW figure. His mother had told him no, to put it back, he didn't have enough money, etc. The boy begged: "But Mom, I've never seen this one before, is there anyway you could buy it as a Christmas present for me?" She told him he'd have to wait and see if Santa got it for him.
I decided to step in and ask: "May I have that figure then? I've been looking all over town for that exact same figure for my son - it's very hard to find."
The mother's eyes grew large and she quickly spat out: "I've changed my mind, Timothy, put it in the cart please." The boy cheered and put it in the cart.
Let it be known, I do not have a son.
Let it be known you guilted a mother who couldn't afford a figure into buying one for her son.
