"I'm thinking about naming my first son Emmy so I can say I've got one. I want Emmy, Oscar and Tony - and my daughter Grammy"

Noah Wyle's quote is a funny way of expressing his desire to have a big household. He is suggesting that he wishes to call his first kid Emmy, so that he can say he has "one" - a referral to the Emmy Awards. He then goes on to say that he would like to have 3 kids, 2 boys and a lady, and name them after the other significant awards - Oscar, Tony and Grammy. This suggests that he is anticipating having a big family, and that he is thrilled to have kids who will bring him pleasure and pride. It likewise suggests that he is a fan of the entertainment industry, which he is anticipating having kids who will share his passion.
