Funny Drinking PSA Sign
This is a funny drinking PSA sign giving a public service announcement that calculus and alcohol do not mix, so don’t drink and derive. This saying has actually been around for a lot of years, a company of mine making Don’t Drink and Derive products for a school a dozen years ago, so it is nothing new. Yet it meets the criteria of a good sign, clever and memorable. I just with they worded it to include not drinking and driving as well. No way to say that enough these days! Even after decade of pounding that message home, people still do it.
