No, it's not a joke. Excerpts from
BBC news:
Condoms, which promoters say can be put on in just one second, are going on sale in South Africa this week.
"Using an ordinary condom is a real pain," says Pronto condom designer Willem van Rensburg.
"By the time the condom is on, the mood is halfway out the window." Pronto condoms do not need to be unwrapped.
"If you're slow, it'll take you three seconds. You can really do it in one," Mr van Rensburg's former business partner Roelf Mulder told the AFP news agency.
