Togetherness is a new HBO drama series that premiered a few weeks ago. In the latest episode (Season 1, Episode 3 - Insanity) which aired last night, there is a Rush reference and Tom Sawyer is played as described in this Entertainment Weekly recap:

... Brett's just had an epiphany (more below), but we don't know what, and Alex has just had his own. Alex says, "I don't know, man. I didn't even realize it was happening, you know?" Brett tells him, "I kinda saw it." They don't even have to say it out loud. It's a fantastic scene for these best friends, especially the otherwise pretty boring Brett, and the visuals crystallize the episode. Brett's driving, and Alex is in the passenger seat. Headlights are shining down and leftward over Brett, and the reflections on the windshield are moving up and rightward over Alex. Everyone's moving in his own direction. Suddenly Brett pulls over to cheer up his bud. He tells Alex that he inspires and delights everyone around him, just like the hero of Rush's "Tom Sawyer."

The episode is available on demand and on HBO Go to HBO subscribers. Thanks to Phil Simon for the heads up.
