This one was told to me by my boss. I thought that it was a perfect joke for my dad, but then thought others might like it as well (Peter Gerrits, Andy Anderson, Ed Gieske, Chris Bilik). I'm not a good joke teller, but it goes something like this:
The CEO of Coors, the CEO of Anheuser-Busch, and the CEO of Guinness are sitting at a bar. The Coors' CEO orders a Coors Light, the Anheuser-Busch CEO orders a Bud Light and the Guinness CEO orders a Coke. The first two CEOs are feeling a bit smug but ask why the Guinness CEO ordered a Coke. The Guinness CEO answers: "I figured if you guys weren't going to order beer, I wouldn't either."Ba-dum-bum!
