There's really no telling if he's actually really interested in space or he just found that hat somewhere and decided to wear it. But honestly, I wouldn't put anything past him. He is the Boston sports scene's new Evan Turner.
And while it's not Halloween yet, Bennett had some fun with the kids at Boston Children's Hospital when he dressed up as Pikachu and tweeted a picture of it.
Given Pikachu's popularity and the resurgence of Pokemon, I'm sure this went over really well. Bennett seems to have a really unique personality and there's no reason to think he wouldn't be good with children.
