Lily: Marshall, I'm sorry. I love you, but I haven't had a second alone in weeks! It's summer vacation! All I want to do is sit in the bathtub and read a book, but now...

Marshall: Baby, I forgot to bring a book. Do you mind reading yours out loud?

Marshall: Hey, it's been no picnic for me either. You don't even do the voices.
