It got me thinking, "How quickly would this be off the shelves (or how certainly it would not have made it to the shelves) if it said 'Grandpa' instead of 'Grandma'..."

Justified? Empirically, I would presume so. But there are other ways of looking at this. Nonetheless, I have no concrete answers, just a brief thought.
