Robin Williams And Ben Stiller Did Something Adorable For Their High School Costar

Ben Stiller helped, too.

Actor Skyler Gisondo had a epic end to his senior year of high school. 

Not only did he get to star as Ben Stiller's son alongside the late Robin Williams in the movie "Night at the Museum: Secret of the Tomb," he also had them involved in his adorable "prom-posal."

According to The Hollywood Reporter, when Gisondo asked Williams to help him, he was so excited. 

"All morning, Robin was pitching more ideas," Gisondo told The Hollywood Reporter. "He was saying 'Can I say this? Would it be appropriate to say this?' You're Robin Williams. You can say whatever you want!"

With a prom-posal like that, who could say no?
