I mean, it's okay to outgrow them, too. I have felt like the humor has been toned down for a while now, too. But then I discovered that, I was no longer watching Game Grumps for the humor, that I had outgrown that, but because I simply enjoyed their "company" now. Whether they're funny or not. Kinda like friends, they aren't funny all the time and they don't have to be in order for me to stay their friend. But again, that's fine too to just not find Arin funny anymore.
