Somwhat he lipsed, for his wantownesse,
To make his Englissh sweete upon his tonge;
And in his harpyng, whan that he hadde songe,
His eyen twynkled in his heed aryght
As doon the sterres in the frosty nyght.
This worthy lymytour was cleped Huberd.

– Geoffrey Chaucer

The Canterbury Tales, General Prologue. Friar Hubert is very aware of the power of delivery in his speech and song, when trying to get cash out of people. He adds a little lisp to make his English sweet on his tongue. His eyes also twinkle like stars in the frosty night (simile) during his performance. If he were in America today, he could be a successful televangelist.
