The fifth and last citation the OED gives for 'transf. and fig.' uses of 'schizophrenia' is from The Daily Telegraph, 1969, Oct. 6, 9/5 -- so expect humour!
The citation goes:
"Bristol's Little Theatre
illustrates the same
i.e. not the London variety
"with the farce "One for the Pot" next
in the bill after Ibsen's "Master Builder."
--- a double bill if ever there was one!
I hope he was not a pot master builder -- and the one for it!
