Click, clack, front and back (seatbelt safety message).
Birds of a feather flock together.
Just a few examples of rhymes from popular culture and community announcements. Rhyming statements are not only more memorable, they are seen as more accurate and truthful.
Imagine if Johnny Cochrane, O.J. Simpson’s defense attorney, had said: If the gloves don’t fit, you must find him not guilty! instead of the more memorable line If the gloves don’t fit, you must acquit!
So if you have a message you want people to accept and remember, use a rhyme.
