Mr. Furley is suffering from Jack Tripper Syndrome and is standing outside the bathroom and eavesdropping while Jack and Chrissy are installing a shower curtain.

Jack Tripper: Okay, Chrissy, I'll get in the tub with you, then we can get it on.
Chrissy: Get next to me, I'll show you what to do.
Jack Tripper: This isn't exactly the first time I've ever done this.
Chrissy: Maybe so, but girls are better at this than boys.
Jack Tripper: Come on, Chrissy. A little less talk and a little more action, okay?
Chrissy: Okay, you do your part and I'll do mine. I don't think it'll reach!
Jack Tripper: Of course not, you've got to unfold it first!
