Spongebob Squarepants just celebrated his birthday and I was shocked to find out how old he is! Thanks to our friends at Buzzfeed.com we have a lot more shocking real life ages of our favorite cartoon stars.

Ok so if Spongebob was a real life person he would be 27 years old.

I keep seeing more and more references to Doug Funnie. I will admit I didn't see Doug but he'd be 33.  However, there is a discrepancy:  In the Nickelodeon version of the show, which began airing in 1991, he's described as 11.  In the Disney version, which debuted in 1996, he's 12.

"Jem" is now 47! That's TRULY OUTRAGEOUS!!!
