Niles: Before you mock this product, you might recall you went to that spa.
Martin: What?
Niles: Don't you remember? Two years ago. For your birthday I gave you that special gift certificate for you and Sherry to have a day of indulgence. You told me you used it.
Martin: Oh, yeah. Right.
Frasier: Remind us, Dad, what treatments did you have?
Martin: Oh, we did the whole shooting match. First, they rubbed us all over, and then they uh, they washed us down with this liniment oil, and then they hit us with those hickory sticks.
Frasier: For God's sake, you've heard us talk about it enough, you'd think you'd be able to bluff a little better than that.
Martin: You'd be surprised at what I don't listen to.
