Speaking of malapropisms, didn't Mrs. Malaprop say "My infection for you grows with each passing day" - or something like that?
She does leave Lydia weeping like an allegory on the banks of the Nile.
In the musical version of THE RIVALS, Mrs Malaprop sings:
Each female creature whom I teach
Develops delicate dainty shapely speech
And a verbal charm as lurid as you've ever known
For a more than ordinary glorious vocabulary
Is a very very necessary thing to own
Her dative case deserves your praise
And the seductive mood she well displays
For men are never contraceptive to a well-turned phrase
So when with a gentleman the little dear is quite alone
She works her little lexicon right to the bone
Men stare but she's quite unaware
As she chooses her words with scrofulous care
Each female creature whom I teach
Develops delicate dainty shapely speech
And a skill to be illicit when she's grown full-blown
For a more than ordinary glorious vocabulary is a very necessary thing to own
