Oh my goodness, what some people will do! I love my wife, she loves me, and we've been married for almost 25 years. But if I told her we needed to kiss for 50 hours straight, well, let's just say I don't think we'd be celebrating our 25th anniversary!

But that's what nine couples in Thailand are doing! They have been smooching it up since Tuesday -- all attempting to set a new record for the World's Longest Kiss! And one of the couples has been married for 50 years and is in their 70s! Pannajet and Suwanna Yomjinda, 74 and 72 respectively, are the oldest couple attending the annual Ripley's Believe It Or Not! contest in Pattaya, Thailand. Suwanna said, "I'm not sure if we'll win because of our age, but if we were younger, we would surely win." The two are aiming to beat the current record -- a kiss that lasted a mind-blowing 50 hours, 25 minutes, and one second, according to Guinness World Records. The event's guidelines allow couples to drink water out of a straw as long as their lips remain sealed. Referees accompany them to a special bathroom throughout the competition. The contest will continue through Valentine's Day -- or until only one couple is left kissing.
