7 Grand Dad, also known simply as Grand Dad, is an infamous bootleg video game made in 1992 from a pirated version of the Nintendo Entertainment System game The Flintstones: The Rescue of Dino and Hoppy. Due to the rather absurd nature of the game, it primarily became a recurring joke on Vinesauce Joel streams and later SiIvaGunner videos in 2014 and 2015.
