16. Sing Karaoke
If you don't have a karaoke machine at home, there's usually a few of them on TV!
Of course, you can always just listen to the backing track of songs on YouTube and just sing over it.
It's super fun and it's always cool to be silly with one another!
If you have a karaoke machine already, make sure you match it with only the best high quality microphones around!
