This gag courtesy of my wife, who once pantomimed this exact situation with a piece of cardboard that looked like a TV screen. This is why we're perfect for each other.
Watching vids of someone else playing games sounds weird if you're old (like me) but I don't see much difference between that and watching actual sports. Or crowding around an arcade cabinet. If anything it's sometimes more fun because in sports you don't get to kill zombies or fly around as a cute dragon.
