These might be funnier in person, but this last week Austin looked in the mirror and let out a big sigh and said, "Ah, man! I need to shave!"
I'm not sure if this next one is from a movie, but he keeps saying, "I wish I wasn't adopted!" I think it's from Despicable Me.
He also thinks that, "I need some privacy," means he needs some clothes. So every time he is getting changed or isn't dressed he yells out, "I need some privacy!!"
