When it's a wagon!
Clyde's tail is a wagon (er, a-waggin') as he waits for somebody to come in.
I wonder who it can be?
Why, it's Grandma!
Hey, Grandma, are you forgetting what time it is?
It's ear-rubbing time! (As if it weren't that time, every moment of every day!)
And it's also time to visit other lovely, loving beasts at Modulator's Friday Ark!
