That would have been the perfect cue to say any of the following:

"You're not getting married?? But a child needs two parents! A married mother and father! It doesn't even have to be a happy marriage!"

"Joey will be disappointed; I'm sure he would have loved to officiate."

"So first a child out of wedlock and now this? There is no hope for you, sir."

Instead, what he ended up saying, completely against his wishes, was:

"Oh, thank God."

...What the hell?
