"leering behind the tea trolley, in a Dick Emery headscarf"

Dick Emery was a hugely popular British television comedian in the Sixties and Seventies. He played many of his characters in drag presenting them as either frigid or over sexed. His brand of comedy would have been regarded as slightly smutty, full of innuendo and double entendre. I'd imagine most people now would find it irritating and silly rather than funny.
