Marriage is just an elaborate game that allows two selfish people to periodically feel that they're not.

I knew instinctively that this could not be correct. Unless you're specifically trying to raise a welterweight, continual deliverance of powerful uppercuts is not advised when handling newborns.

The most challenging part of being a dad is trying to postpone the moment when they realize you don't know anything. I love any sentence that begins with Daddy...? because it's implied they're looking up to you - that you'll have the answer. The truth is, I don't have any answers.

The most rewarding part about being a dad is just looking at children who didn't exist at some point. The first time you saw them, they were the size of a quarter, in a sonogram, and now they can pour orange juice and yell at each other.

In the original draft I was 27 and Peter was 55 in the script. That's not the same as a guy in his 40s and a dad in the end of his 70s. It's a different point in both our lives.
