Ah, Switzerland, the land of chocolate, cuckoo clocks and, if you ask nicely, Big Macs served with a healthy helping of cunnilingus.

On Saturday, patrons of a McDonald's in Zuchwil, Switzerland were surprised to find a television playing pornography "at full volume," the country's 20 Minnuten reports.

Apparently the result of (unexpected) adult programing on a customer-requested sports channel, the sexy mistake went uncorrected for about an hour.

According to a McDonald's spokesperson, restaurant TVs are usually tuned to the largely porn-less Eurosport network, but employees sometimes change the channel "to please a customer."
