'Suite Life of Zack and Cody' stars graduate from New York University

NEW YORK -- Get ready to feel old: Cole and Dylan Sprouse, the twin child stars of Disney Channel's Suite Life of Zack and Cody, are college graduates.

The twins posted Wednesday about their graduation, prompting fans to reflect on just how much time has passed since they played little boys living in a hotel and getting into all kinds of shenanigans.

Though the twins, 22, are best known for their roles as Zack and Cody in the first Suite Life series (2005-2008) and its sequel, The Suite Life on Deck (2008-2011), they also had memorable appearances in the film Big Daddy and the TV series Friends.

"Smarter better faster stronger. Finished NYU now on to the next," Dylan posted on Instagram.

He also posted a gold tassel he earned for academic achievement.
