When he thinks something sounds good he says, "That sounds like good!"
We were at Toyota waiting for our car to be serviced and he was looking into the garage and thought it was kind of weird. He then went around asking everyone if they were, "scared about the garage."
He likes to randomly smile and say, "I love you Mommy, I love you Daddy, I love you Baby Sister!"
While we're eating lunch or dinner together, he'll all of a sudden say, "FAMILY HUGS!!!!" at which point it's our obligation to get up and give him a big hug at the same time.
He calls hamburgers hangubers.
Sometimes while listening to music Parker will randomly say, "I LOVE this song!" when a new song comes on.
