Roz: I'm on my way to meet Alice and her sitter. Alice wants to practice riding her bicycle for Saturday.
Frasier: Really?
Roz: Mmm-hmm, she loves it. I mean, she had that bike one day before she made me take her training wheels off.
Frasier: Tell me, does she ever find that she feels as though her feet are frozen to the pedals? Stuck in a confused, arrhythmic battle between forward and reverse, until finally, with no locomotive momentum whatsoever, she keels over like a felled tree?
Roz: I don't think so.
Frasier: Well good, good. Because... that's a real thing that happens to some kids.
