Coolest grandfather ever. Michael Temby performs a series of intricate dance moves while on waterskis all captured by a camera strapped to the back of a jet boat. One-handed, backwards, upside down—it’s all caught in a one-minute GoPro video. Jump to 0:50 for the jaw-dropper: he has one foot hoisted onto the rope with two hands gliding behind him on the water. Talk about engaging the core.
