Swedish pharmacy seeks volunteers to break world longest kiss record As part of a new campaign to promote dental hygiene, Sweden's largest pharmacy chain Apoteket is looking for volunteers to pucker their way into the record books with the world's longest kiss. The present record for the world's longest kiss now stands at just under 31 hours. A pharmacy spokesman said that the kissing record stunt is part of a campaign promoting good dental hygiene. The couple who are lucky enough to be selected for the megakiss will get kissing coaches, along with tips on flossing and better brushing.
