Season 7, Episode 5: "The Hot Tub"

-It's like a furnace in here. -What the hell is going on?

I turned up the heat.

Turn up the heat in your own apartment.

I just need to get my hot tub running.

I'm waiting for my new heat pump.

Well, what's in this giant box out in the hall?

-Oh, that must be it. -It's huge.

Yeah, I got the biggest one they had. Yeah, it's industrial strength.
