I saw one of these posters on 10th or 11th Street east of Fifth Avenue in Park Slope and it caught my eye.

It’s an image of a cartoon boy seen shouting “DON’T DRINK &#%+! DRINK WAT-AAH!”

I thought it might have something to do with that soft drink tax Paterson is proposing.

Then I thought it was an ad for a new product called WAT-AAH.

But now I get it. It’s a public service announcement encouraging people to drink water. Is WAT-AAH water with a Brooklyn accent or a baby crying or…

This campaign has an interactive element. You can fill in the blank…

“Don’t Drink ____, Drink WAT-AAH!” is WAT-AAH!’s new advertising campaign. This campaign encourages parents and children to fill in the blank with words such as “Soda,” “Sugar,” “Junk,” and even “&#%+!”

Someone is taking a stand against childhood obesity and other health issues, WAT-AAH! says that there is an alternative to soda and other sugary drinks… all while being fun, too!
