PICTURE: Friends Fan? This Will Make You Feel Completely Ancient

Boy do we feel old! Fans of hit TV sitcom Friends will certainly remember Ross and Carol and their little son Ben. When the show first kicked off we met Ross, who had just broken up with Carol and was learning to deal with fatherhood and the relationship between Carol and her new girlfriend Susan. Ben featured in a number of episodes as he got older and now, it's us that are feeling old as here's what Ben, or rather 23-year-old actors Dylan and Cole Sprouse look like now. The twins, who celebrate their 23rd birthday today, first found fame as Julian, opposite Adam Sandler in 1999 comedy Big Daddy.

The pair, who also starred in The Suite Life of Zack and Cody graduated from New York University in May. To make the big day a little more interesting, they decided to accept each other's diplomas.

Cole, who studied archaeology, confessed to the prank in a recent interview with Teen Vogue. Dylan, who studied video game design, added: "In fact, if you look up my graduating photo you’ll see."

"We just decided, you know, there’s no reason not to. No one’s going to notice."

Anyone else feeling ancient right now? You can follow "Ben" on Twitter here and here.
