Email that made me laugh. . .hard

I received an email today that caused me to have to take several minutes to just laugh. It was from an old friend who was able to make it to my wedding and we have been catching up of sorts. By that I mean we have been swapping movie quotes and old stories. See if you can tell me what movie these two quotes are from, and if they cause you to laugh as hard as they did me.

1. "I wish I could belive you, but unfortunately I can't."
2. "I think the kids really appreciate it when I 'get down' with them verbally."

By the way, stay clear of Nebraska. You don't know what you are getting into, trust me.
