When Columbo and Joe Devlin went out for their evening together, was Columbo really boozed up or just acting? I would have liked to have seen an episode where he gets trashed, would be hilarious. He'd forget where he left his raincoat!
I believe he "forgot" where he left his new raincoat in Greenhouse Jungle!
I don't think he even had the new raincoat yet, during the time of Greenhouse Jungle.
