Most ads found in public toilets are taxi services or "erotic services", so it is fair to assume you might be confused by this message found in public restrooms in the US:

Not only does the ad suggests an extraordinary fetish, but the site does little to allay your fears. iwanttobeababy.com houses a range of videos featuring adults behaving like babies. It is meant to be funny rather than arousing, and eventually leads you to a lovely environmentally friendly baby clothing brand.

The idea is that people don't completely lose their sense of humour when they become parents. The videos are supposed to provide busy working folk with a giggle when they see grown adults behave like babies. That, in turn, is supposed to remind the grown adults of the simple pleasures of being a baby.

It's slightly convoluted, but refreshing once you get there. Most baby care brands focus so much on cute picture of kids with flowers and animals that any wit goes out the window.
