Eric: [to himself] Okay, think, Eric, think. Why kitty litter?
Red: [imaginary] Use the gum, Eric.
Eric: Dad? What're you doing here?
Red: I'm not here. You're imagining me. Now who's insane, Mr. Smartmouth?
Eric: I guess I am.
Red: Use the gum to stick the candle in the can. The candle heats the can, which melts the snow behind the tire. Then pour on the kitty litter for traction. Now you think you can handle that?
Eric: Yes, sir.
Red: Good. Because you don't want me back out here. I may be a figment of your imagination, but I'm still freezing my ass off.
