Adventures in Babysitting is a special movie, not only because it stars our favorites Sabrina Carpenter and Sofia Carson, but also because it's the 100th Disney Channel Original Movie. The Disney Channel threw a whole extravaganza for the momentous occasion, and a bunch of your favorite throwback DCOM stars were there.

Some of them, you probably haven't seen in a very long time — it's so shocking seeing what they look like now!
