C, Eb, & G go into a bar.(Thanks to a brother named Joe, who posted this on our fraternity listserv today.)
The bartender says “Sorry, but I don’t serve minors in here," so the Eb left.
The C & G decided to open a fifth between them.
This might sound like a joke, but isn't: A new world record was set in British Columbia last month, when 644 people played accordions simultaneously for half an hour.
