Stopping a dog.
"Sit, dog, sit. Good dog."
"Stop! Stay."
"Heel!"

On seeing a spider
"Eight legs because you're too stupid to stand on two."
"I hate hairy things with more legs than me."
"A whole lot of legs, but you're still ugly."

On squishing a spider
"That's why I'm still top of the food chain."
"Me, one. Eight-legged fiend, nil."
"THAT'S for being ugly."
