Stanley and Dennis in “Show-and-Tell Shark”

Tyrannosaurus rex is the mightiest dinosaur ever. I'll take him to school on a leash.

And then when you get there, he'll flatten the place, and eat your teacher, and everybody else in sight.

Oh. Well, maybe you're right.

And besides, Tyrannosaurus rex has been extinct for 65 million years.

Extinct?

Not on the planet. Outta here.
