Psht, that's my kid's favorite excuse! The other one is "That toy is the ugliest, most obnoxious piece of crap I've ever seen, and I wouldn't bring it home if you traded your leg for it."
They seem to have survived thus far...
Who are these whiny people?!? One of the great joys of my life is saying, "Are you out of your mind? There's no way on earth I'd buy you that, and you can't buy it with your own money, either! Obviously you haven't been paying attention for the last 8 years in our home, so you can clean all the bathrooms for the next week in order to focus your mental processes!" (Have a nice day ...)
I think I also say, "No, we're not getting another snake!" at least once a day, and you can't blame that on advertising.
