Leopoldo Buosanti Neto, owner of the bar Boteco Brasil in São Paulo, noticed that his clients would often run outside when they received phone calls, since many didn’t want their spouses to know where they were–especially the male customers. So he invented the Cabine Cornofônica, an English-style telephone booth that produces different sounds meant to trick callers into believing that the bar’s customers are anywhere but the bar. It produces airport sounds, with flight announcements and planes taking off, traffic noises with horns honking, a gun fight with sounds of shots, and even the sounds of a woman shrieking…with pleasure.

Apparently, the special phone booth has become very popular with clients, who use it to lie to their spouses about their whereabouts. Though it is most popular with men, women frequently use the phone to lie to their boyfriends and husbands, too. They most frequently use the traffic function.

However, some clients are skeptical, and one claimed the sounds from the phone booth were too muffled to trick the cleverest listeners.
