Al Gore

Grayson has been very vocal lately and loves when you mimic his sounds. He looks at  you like you're having a real conversation and he understands every word. 

Other vocalizations include fake crying and coughing which is so obvious he laughs or smiles afterward if you call him out on it. He's also said his first word and it was actually two words, "Al Gore." 

I tried to explain to Michael that this was probably just a version of "ah gooh" but he's convinced it was really a reference to our Nobel Prize-winning former VP. You be the judge.
