You may think subway grates look nasty, but 'Surprise Party Specialists' in NYC found a way to make the grates a good time. Whenever the subway cruises by, streamers surprise you from the grate. The ad, developed by GJP Advertising, is innovative and well connected to the value proposition.

Implications - These pop up streamers will definitely add a hilariously fun party mood to the streets. I bet you can imagine the pranks that would ensue as people set up tourists to be shocked by the unsuspecting streamers. Hopefully Surprise Party Specialist have also developed a way to keep these street decor from getting filled with dirt and grime.
