ATDDTA(11) "Grundyesque screaming" [303:23]

[Keith]

Mrs. Grundy is an imaginary English character who typifies the  
censorship enacted in everyday life by conventional opinion. She  
first appears (but never onstage) in Thomas Morton's play Speed the  
Plough (produced 1798), in which one character, Dame Ashfield,  
continually worries about what her neighbour Mrs. Grundy will say of  
each development.
