Eight is a bard's delight.
To start the ball rolling on a database of malapropisms...
abrogate, alleviate, date (as in the anatomical location e.g. the eight's date of appointment), debate, defecate, deflate, delineate, discombobulate, illiterate, inarticulate, inappropriate, levitate, obfuscate, permeate, prostate, prostrate, regurgitate, relegate, resuscitate, sate, wait ...there must be more in the MEL.
So rotate ye bards
