Aside from all the gaming announcements coming out of E3 2010 today, it’s also Flag Day in the US. To celebrate, here’s a quick joke to get things going: “What did one flag say to another? Nothing. They just waved.” For more buzz regarding this event, check out the Twitter stream.

Although it is not a national holiday, Flag Day celebrates the day that the American flag was officially adopted by the Continental Congress in 1777.
