July is Cell Phone Courtesy Month

Excuse the interruption to your conversation there, pal, but I thought you'd like to know that July is Cell Phone Courtesy Month. "It's a time for those who just have to stay in touch, wherever they are, to pay more attention to the highway if they're driving, and to hold down the volume of their conversation if they're in a public place."

2005 Update: or you can smile while you're telling the person off.
