Sebi and Paul, the hilarious duo from the continuing Switzerland Tourism campaign, who we last saw trying to take down every clock in the country, are back, and they're sleeping. Digital agency Eyekon challenges you to wake them up via a special site, between the hours of 7 p.m. and 7 a.m. Swiss time. The aim is to illustrate just how relaxing holidays in Switzerland are, so relaxing, in fact, that you'll sleep like a marmot.

On the microsite, which is available in six languages, type in any text -- and see what happens. We started with trying to rouse them with a "party," with hilarious results. There are even prizes up for grabs.

The duo's previous exploits include this Bronze Lion-winning spot that showed the country men enjoying the city's urban pleasures, while an online campaign cleverly integrated chatting and Facebook content.

Previously, the agency also introduced us to Swiss weather prophet Martin Horat, who told us what ski-season in the Swiss Alps will look like, using a very interesting method. All of those efforts were out of Spillmann/Felser/Leo Burnett.
