The Milwaukee Brewers just won their first playoff series since 1982. I just wanted to point out the M and B in their old logo. I thought I was the last person to figure this out, but there's a Facebook group called "Best Day of My Life: When I Realized the Brewers Logo Was a Ball and Glove AND the Letters M and B." Perhaps this is now the best day of your life.
Here are some other logos with "hidden" messages, like the FedEx arrow and the 31 in Baskin Robbins.
