I wonder if kids who grew up with Mario during the 80s and 90s became more likely to become plumbers by trade as a result of the games, tv shows, and of course the movie. My guess is probably not by a significant margin, but it would be interesting to see statistics or whatever.
I also wonder if parents became more likely to name their children "Mario" or even "Luigi" as a result of the franchise... I'm pretty sure that in the English speaking world these names would probably be largely unknown otherwise.
