K-OLD is a radio station only featured in the episode "Mid-Life Crustacean."
K-OLD appears to play old songs, in order to take individuals back "to the good old days."
In the beginning of the episode the radio man says "You're tuned in to K-OLD, K-OLD, the all oldies station taking you back to the good old days" when Mr. Krabs wakes up from his sleep. "You're Old" then plays as Mr. Krabs opens his eyes.
