Morning-Gotchoo mystery solved!

After about 3 weeks of Zach calling his scooter his "morning-gotchoo", and us, trying to figure out where the heck he came up with that phrase, I've finally figured out what he's trying to say.
Are you ready?
Wait for it...
"MOTORCYCLE!"
We saw one in the car today and he pointed at it and said, proudly, "morning gotchoo!"
I am so on top of it.
