David Wiles' researches about the clown in Shakespeare are used to provide confirmatory evidence that Sonnet 20 was a tease. It is suggested here that, being based on the 'jig', it was a mock courtship ritual. That fits the occasion of William Herbert's sponsored courtship of Lord Burghley's granddaughter in 1597. As a ritual tease the sonnet cannot be treated as a source of information about Shakespeare's personal feelings. The problems of lines 7 and 9 are solved by Beeching's verbal restoration instead of by the usual changes of orthography and of sense. It is argued that the unity of the poem and its social and historical contexts make it wrong to find bawdy meanings in every possible word or phrase, which anyway would spoil the bawdy joke which is the sonnet's (double) climax.
