Whad's dat?

I really really want a dime each time I hear this in a day! Rex is on a rampage of asking questions. Bedtime stories are now just a labeling exercise. In 5 minute intervals you will hear some what intelligible "What's that?" or "What's name?" So very very cute the first 2-3 days and excited to teach the little guy but now I just go with "I don't know"
