Even if you're not a fan of late night TV, it's great because you can see the cool moments on the internet.

Take, for example, Late Night with Jimmy Fallon.  A few nights ago, he had singer Ariana Grande on the show.  They did a segment where popular songs were turned into Broadway-style songs; stuff like "99 Problems" and "Thrift Shop" were turned into piano-friendly and musical-friendly songs.

It's pretty cool to hear, especially if you've ever sang along with those songs (admit it, you know you have...)
