How old is spongebob squarepants?

SpongeBob creator Stephen Hillenburg explained that he didn’t want SpongeBob to have a specific age. The character was supposed to be overly optimistic and child-like, and slightly annoying.

However, when SpongeBob’s driver’s license is revealed in an episode, it lists his date of birth as July 14, 1986, which would have made him 12 years old when the show premiered on May 1, 1999, and 25 years old in the present.

Originally, the character was supposed to be named “SpongeBoy,” but Nickelodeon discovered that the name was already being used for a mop product. They really wanted to keep the “sponge” as part of the name, as they were afraid that some viewers would mistake him for a block of cheese.

Many celebrities have made guest appearances on SpongeBob SquarePants, including John O’Hurley, Marion Ross, Tim Conway, Alec Baldwin, Christopher Guest, David Bowie, Davy Jones, David Hasselhoff, Gene Simmons, Scarlett Johansson, Johnny Depp and Ray Liotta.
