Force of habit maybe? It honestly sounds like having Arnold Schwarzenegger as a dad is like being related to an action figure. He has these huge lines he can pull out of his back pocket to create a memorable interaction with fans, and he’s doing it all the time. What’s hilarious is apparently he actually uses his “I’ll be back” line a ton… like just to exit a room while he’s with his family. I mean, if anyone has the right to say it, it’s him.
