"Let your pee do the talking.."

Has anyone seen this ad at any of the bus-stops recently? Well, one of such caught my attention. Thought it's pretty unique & catchy. Wonder which ad agency came up with this idea :) Will try & take a photo of it when I next see it. For those interested, can always log on to their website at http://www.bio-test.info/ to check out the company's products.. Hehe.. Nevermind lah.. Free advertising for them lah :)
