Back to Japan and its brilliantly innovative take on condom design, and as if it isnt disconcerting enough to encase your penis in a florescent yellow sheath adorned with the face of a worried-looking cartoon character whose catchphrase is worship the magic conch!, these condoms are sold in a can rather than a packet, presumably just to whack the creep-out factor up to ten. Imagine, if you will, that awkward moment during foreplay when you have to fish around for a spoon to prise up the ring-pull only for it to snap off in your hand, forcing you to spend twenty minutes tearing apart your kitchen in an increasingly flaccid attempt to locate your can opener. In extreme cases, it might even lead to the humiliating need to knock on your neighbour's door to borrow one. Still, its not as if Spongebob the cartoon series is afraid of slipping in a bit of sexual innuendo; alongside jokes about coin slots and dropping the soap, the character of Patrick Star once created a phallic sand sculpture using only his tongue. Spongebob rubbers? Somehow it makes perfect, if terrifying, sense.
