Actor Zac Efron and his younger brother Dylan busted their grandfather out of nursing home for some fun. Efron shared a hilarious video on Instagram on Tuesday of the incident. In the clip, the actor tip-toes around the facility, does his best to go unnoticed as he crouches low before swiping a staff member's ID to gain access to his grandfather's room.

The video has the title track of "Mission Impossible" playing in the background. "Let's bust grandpa out of here," the star said in the first few seconds of a video he posted on the photo-sharing website.
