A cartoonist, with this cartoon in the May issue of Funny Times:
This works pretty well as a pun in print — Oedipus Rex / Oedipus Rx — with the mother theme and the prescription theme combined. Apparently there are people who treat the abbreviation Rx as an initialism /ar ɛks/, a noun meaning ‘prescription’ (“an Rx for Viagra”), and for them Oedipus Rx works as a (moderately distant) pun in pronunciation as well.
Now: more on this, a note on the cartoonist, and a couple more punning cartoons from him.
