You go through constant “That-Was-Hilarious-What-a-Goofball” phases. This means that every time you learn to do something new, you do it over and over again for a while until you learn something else. Over Christmas, you sang “Ice, Ice Baby” repeatedly (the Jim Carey version) and did all of the dance moves. Before that you would lift your arms up like you were flexing your muscles and say, “Strong!” because you saw it on a Wiggles video.
The other night at dinner, The B’s showed me your newest one. It goes, “Liam, do have a bird in your mouth?” (Why a bird? I have no clue whatsoever). Whenever someone asks you that, you stick your tongue out. Then we all laugh and someone says, “That was hilarious! What a goofball…”
So naturally, when things get goofy, I have to join in. :)

The bird in your mouth is better than the “Bonk!” on your head! The bird is imaginary. The “BONK!” however, well . . . that’s real! (Ouch!)
