finding an episode!

Hi all! I'm looking for an episode of garfield where a certain character walks into a pharmacy and take a number to be served. The person attending starts calling: number one, number two, etc., and does not serve the character because he had the number 40 and had to wait for him to finish the count, hahahaha! Maybe its a quickie, I don't really know. Hope tu remeber which episode.
Grettings all! ^_^
