Grandma: "Hi honey, how was your day at school?"

Dormouse: "Johnny and Jimmy and Jackie got to go on a field trip with the six year olds today."

Grandma: "Where did they go?"

Dormouse: "On a field trip."

Grandma: "Where?"

Dormouse; "On a field trip."

Grandma: "Where did they go?"

The Dormouse turns around and leans into Grandma's face:

"ON. A. FIEEEEELLLLD-DAH.

TRRRRRIPPPPP-PAH."

Grandma (amidst my gales of laughter): "Well, I know what a field trip is, where did they go on their field trip?"

Dormouse: "Oh.... the zoo."
