Anyone who's ever gone to ridiculous lengths to try and get a free Wi-Fi signal on vacation will identify with Deutsche Telekom's latest campaign. It features a South American businessman who comes up with the idea of "Wi-Fi Dogs" -- sniffer dogs for hire, which specialize in finding Wi-Fi. A series of online films profile the attempts of the company to rent their (cute, but hopeless) canines to desperate gringo tourists -- with hilarious results. DDB Tribal, Berlin devised the campaign, promoting the company's "Travel & Surf" product for mobile internet abroad.
