The Dinosaur Did It Or so says Imogen, when she needs someone to blame... but that's not very fair to the dinosaur, is it?

"What happened here?" asked Dad.
"Well," Imogen began, a funny feeling swirling deep down in her tummy, "what happened was . . . "
". . . a dinosaur did it," she said.
"A dinosaur?" said Dad.
Imogen nodded. "A dinosaur."

It's very convenient having a dinosaur to blame when Imogen's big mess takes over the house. but it's not so convenient when that blamed dinosaur takes offense and won't leave Imogen alone
