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.
