American Dad!, Season 6

Steve:
Okay, how about this for a case: Wheels's ex comes to town, looking for whoever poisoned her race horse.

[Roger gives an uncertain mumble. Steve thinks for a moment, then comes up with a new idea for a case.]

Steve:
Hey, what if I'm visited by the ghost of my dead father, who also used to be a detective?

Roger:
So we're just saying the first thing that comes into our minds? Okay. Tickle monster!

Steve:
[To someone invisible beside him] I know, Dad, I have to deal with this every day at the agency.

Roger:
YOUR GHOST FATHER IS NOT HERE!!!

Steve:
Oh no? Then who's... [gets up from his wheelchair] ...possessing me!?

[Steve begins slapping Roger in the face over and over by flapping his arm by Roger's face.]

Roger:
Stop it... Stop it, Wheels... Stop it...! Wheels...! STOP IT, WHEELS'S FATHER!!!
