Smitty Werbenjagermanjensen is a legendary figure from the SpongeBob SquarePants episode 'One Krabs' Trash,' first aired in 2002. In the episode, Mr. Krabs invents the character to scare SpongeBob into returning a valuable soda drink hat, only to discover that Smitty was a real person buried with the prize. The meme centers on the phrase 'He was number one!', which has become an internet shorthand for acknowledging someone’s undisputed greatness or mockingly celebrating a minor achievement. It is often used to crown oneself or others as the best in a specific niche, or to reminisce about forgotten legends of pop culture.
