Amen to that, noodle.
My husband got hit up awhile back by a total stranger, after a very long casual conversation in the Home Depot toilet department. This one wasn't even selling things, it was somehow based on website logins. But he was fairly livid when it suddenly dawned on him that this wasn't just a really overly friendly guy who liked talking about the vagaries of home plumbing. Pyramid schemes are a bit of a sore spot with him--as a child, his mother and father both bought into Amway completely, and it really hurt them financially.
And yet he still swears that their vitamin products are the best you can buy.
And my mother recently got sucked into an organic skin products pyramid scheme, but she pretends now that she only joined because she wanted to use the products, and figured it would be better to buy from herself than someone else. Yeah, uh huh.
