Let’s check out Subway’s Hand It-ad with their campaign for the $5 footlong.

This became an insanely popular campaign, because of the catchy jingle and poppy tune. People were able to easily recite the lyrics while using the same hand gestures in the commercial. It was a genius way to have people spread the deal by word-of-mouth (and hand). People could even do it silently by holding up one hand, then mimicking the sandwich measurement with two hands.

Good Hand It work Subway. Now just stop making your sandwiches shorter than promised.
