Contraceptives should be used on every conceivable occasion.

In keeping with Spike Milligan’s comic persona, the line reads as an exaggerated, deadpan prescription: treat contraception not as an occasional precaution but as something to be deployed at absurdly broad times (“every conceivable occasion”). The humor depends on overstatement and on the incongruity of applying a serious, private matter with blanket literalism. It can also be read as a satirical jab at social anxieties about sex, reproduction, and moral regulation—pushing the logic of “be responsible” to a comically impossible extreme. Without a verified original setting, it’s best understood as a standalone Milligan-style one-liner rather than a carefully argued position statement.
