It's a creative copy, but will it wok?

Found on another sub about a copy that was hailed for its creativity. A hoarding board said:

The truth about life is that shit happens every day. Talk to us, if it doesn't. (Clinic name) (Gut wellness clinic)

My reasons for why it may not work: it's not easily understandable quickly at a single glance. And most people travel by vehicles - not many are going to stop and re-read it to catch the pun.

Or am I wrong? If it can work, then how? Should the hoarding board be placed at areas where people don't move much? ( near traffic signals?)

Edit: work*
