Frasier: Niles, we can't stall much longer. I mean, one seems as good as the next. Is there anything else we need?
Niles: Hmm, let me see. Oh, yes, I know. We need to know how to ride them!
Frasier: Shh. We will learn.
Niles: Oh, as easy as that? Look at these machines, Frasier. These are bicycles. There is nothing between you and the ground but the ground itself.
Frasier: Yes. And if a child of four can ride one, then so can we.
Niles: That's what we said when we were six.
