"You're on thin ice, Dog Man. So don't mess this up. Now, sit! [Dog Man sits on a desk chair, which spins] Stay! [The chair comes to a stop] You only have one job to do: keep your eyes on those monitors. [pulls out a rubber ducky] So, if somebody breaks out your favorite chew toy, and waves it around, you… You look at the monitors! [pulls out a bone] And if somebody has a juicy and delicious treat, you're not gonna look at it. You… You look at the monitors! [takes off his hat, revealing an Eastern gray squirrel on his head] And if somebody just happens to have an Eastern gray squirrel, you… [grabs Dog Man, who tries to get the squirrel as it scurries away] No! Dog Man! Just sit here, and don't mess this up, or you'll lose your job!"

"I need someone, who thinks like me, acts like me, and has a retched soul like me. I need another me!"

"[Li'l Petey: Do you have a car seat?] A what? [Li'l Petey: A kid's car seat.] You're a clone cat sitting in a flying mechanical bug. They don't make a car seat for that. [Li'l Petey: OK, Papa.]"

"Dog Man, get in here! Now!"

"Will you get outta here?! Go and arrest Petey, AND I DON'T CARE IF IT TAKES A MONTAGE!"

"Why do you always gotta lick the… [spits, censoring himself] …inside of my mouth?! [Dog Man grunts "I don't know"]"

"[from the trailer] This super-cop makes friends, solves crimes, and even plays piano for the old folks."

"Maybe, Flippy… Maybe you just need a friend."

"Where are you, Petey, the World's Most Evilest Cat?!"

"[repeated line] Relax. We will be fine."
