You have to love a game of ping pong, especially when there are no actual ping pongs being used to play it! In fact, the match these two are battling out also has no paddles, net, or ping pong table at all! All that is required is an imagination and optional sound effects (like these two do an amazingly accurate job of!). I love games like that, do you?
On a long drive once, my friends and I came up with a game (that no doubt many others have) where one person came up with a situation of something (anything), and then we went back and forth naming books or movies or songs wherein that occurred. So, for example, “a whale.” Then you could say (spoiler alert!) Moby Dick, or the Squid & the Whale, or Free Willy, etc. etc. or “suicide”, or “baseball.” It’s pretty basic and kind of mind-numbing, but it passes the time.
