Columbo:  Say , you know , 's a funny thing about your appointments with Mrs. Kennicutt ? Uh , the first _ two _ were in the morning and all the rest - and I counted thirteen of 'em - uh , they were always in the middle or the late afternoon .
Ken Archer: So ?
Columbo: Uh ... Well , I guess it 's not important . I guess it 's nothin' . Wait , let me ... I 'm gon na take off my coat . Except that , uh ... you know , every time you had an appointment with Mrs. Kennicutt , it was always the last lesson of the day .
