@dalehileman,
Oh, you're British I take it?
To you everyone in America is a Yankee, huh?
Here's the rules are different.
I'm conflicted as far as my Yankeeism, as I was born above the Mason Dixon line, but haven't voluntarily stepped North of it (except for maybe a total of 2 weeks), in over 35 years.
And no, I'm not surprised to hear an ad that says something will change your life. I would just hope that the ad would be for something like a treatment for lung cancer, no risk sure fire birth control or a car whose byproducts clean the environment. Not for a bbq grill.
