Zac Efron posted a video of himself and his brother busting their grandpa out of his retirement home . . . "Mission Impossible" style. At the beginning of the video Zac said, quote, "Time to bust grandpa outta here." Cue the "Mission Impossible" theme song and a classic somersault. When they got to grandpa's room, they "snuck" him out in a wheelchair to the car. All for grandpa to enjoy a cold swig of Coke and watch the Euro 2021 finals with his grandsons at their home. Zac said at the end that, quote, "Grandpa is better at acting than I am." This is the sweetest video I've seen in a long time. I just loved it. Check it out below!
