Take on Period-proof underwear ads

Anybody notice the new period-proof underwear ads on the subways this month? I get that this is probably areal issue but I'm not sure anybody needs to be confronted with this on a Tuesday at 7:30am right after I had an egg and cheese with ketchup.

But that is not the worst of it because as much as I am not ready to be confronted with this at 7:30am myself, I am definitely not ready to explain it to my six year old and we all know they will immediately ask you when they read that sign. It's like all those viagra commercials during every NFL game with a guy throwing the football through the tire swing as the sun sets over his farm. She has asked me to explain that one already and I had to come up with some crap about the guy having hurt his shoulder and now able to throw a spiral again with the help of that pill.
Whatever happened to the kind of wholesome Marlboro and Joe Kook ads of my youth??
