Don't you hate it when you're riding to work on the subway and you suddenly have a diarrhea attack? Here's an ad for anti-crap-your-pants medicine called "Stopper."
I like how the bottom of the ad directs people to download a toilet locater app for their smartphone. From my experience, it seems more people here vomit on train cars and platforms than blow a gasket, so they really should be marketing barf bags instead.
