My sister and I imagining how David Tennant might be with his kids:

Child: Daddy, where do babies come from?
DT: WELL...it's all sort of...wibbly wobbly...timey-wimey...stuff.
Child: Daddy, let's go to the Statue of Liberty!
DT: whatever you do...don't blink.
Child: Daddy, why can't you open the door? Did you forget the key?
DT: No...it's just that...it doesn't work on wood.
Child: Daddy, are we there yet?
DT: VWORP VWORP
