Richie: Yes , well , maybe my mime was a little indistinctive , yes , but you know , I mean , it was worth the daytrip to Birmingham just to find a chemist who did n't know us , you know ! I mean , it might have been a long way round just to buy a threepack of johnnies we never use , but I 'll tell you what : there 's been no piles in this house since _ 1977 _ !
