Pedestrians near Lanzhou’s Maryland Stadium got 12 unexpected seconds of titillation when the naughty pictures appeared on the giant screen, Metro.co.uk reported.

It would be funny, if it wasn’t in China – a country where internet porn is banned.

As a result the screen operator has been jailed for 15 days and ordered to pay a fine of ¥3,000. You might say he had a hard day at the office…

Fortunately for the world, a quick-thinking Weibo user was able to document the gaffe. Good work Sir.
