Shakes versus Shav (1949) is a puppet play written by George Bernard Shaw.

The play runs for 10 minutes in performance and comprises a comic argument between Shaw and Shakespeare, with the two playwrights bickering about who is the better writer as a form of intellectual equivalent of Punch and Judy.

The play was written by Shaw for the Lanchester Marionettes who were based in their own theatre in Foley House, Malvern, Worcestershire, England.

Shaw often participated in these skits, by lending costumes, or even writing dialogue for one entitled His Wild Oat (1926).

[3] William Shakespeare arrives in Malvern, seeking the upstart Shaw, quoting lines from his own plays.

Shaw replies that Shakespeare could not have written Heartbreak House, and creates a pastiche of his own play with the characters posed in imitation of John Everett Millais' painting The North-West Passage.

Shaw ends by quoting Shakespeare's own words and bringing into being a small light to symbolise his own reputation.
