Japanese WWII propaganda to demoralize Australian troups by suggesting Yanks were screwing their women while they had to make do with New Guinean ones in the jungle (NSFW)

Serious, this was real:

Send condoms to space to teach alien invaders safe sex with hot earthlings, Swedish group urges NASA

Right…

The Swedes are asking NASA to send condoms into space because they feel the aliens might find them “handy” if they ever decide to come to Earth and have sex with “some hot earthlings”.

[…]

Of course one flaw in the plan seems to be that condoms are already on Earth, so should the horny aliens ever make their way here, we’ve already got them covered … so to speak.

Yeah.
