So, according to one of the banners at the Toronto Zoo, you’ll be getting half price admission on Monday to Friday when 97.3 EZ Rock radio station predicts a temperature of MINUS 97.3 degrees Celcius or below.
At almost 100 degrees Celcius below 0, I’d be staying in my bed under tons of blankets! LOL! Then I’d call the zoo to see how many people show up to get the half price admission … 
BTW, they actually meant “minus 9.73 degrees Celcius or below”. I think the QA team just needed more coffee when they signed off on the sign.
Hmmm .. I should find that picture I took of a funny sign in a tradeshow – it kept me laughing for a while. Where did I keep it …. hmmm.
Maybe the error was intentional… to get people’s attention. It certainly got YOUR attention.
