Today is Scooby Doo's 40th birthday. That's right, Scooby Doo first aired on Saturday, September 13, 1969. I guess it is also a birthday for Shaggy, Daphne, Fred, and Velma.
In connection with the event, Warner Brothers is releasing Scooby Doo 3 today. You can catch it on Cartoon Network. It is a prequel. Don't miss it.
