The Old Man is a character who appeared in Garfield's Halloween Adventure.
He told Garfield and Odie a spooky story about ghost pirates. He is 110, as he was a 10 year old cabin boy on a pirate ship 100 years ago. Before the ghost pirates could arrive at midnight, the old man escaped on Garfield and Odie's rowboat.
When Garfield and Odie finally arrived home, Garfield turned on the TV to see what was on. After finding the old man hosting an all-night pirate movie festival, Garfield quickly turned it off.
