What's New Scooby Doo? Easter Egg - Tweety in Scooby Doo

In the episode, when a guy in a van drives up to the gang, he opens a paper that shows the rare birds he's seen, and one of the birds on there is Tweety Bird! This is very cool because the company that made Scooby Doo (Warner Bros.) also made Looney Tunes, in which Tweety is a character. Even more cool, earlier in the episode Shaggy and/or Scooby saw Wile E. Coyote chasing the Road Runner, other characters of Looney Tunes.
