Couples in Thailand have been attempting to break the World's Longest Kiss Guinness World Record for nearly two days.
The current record is a single kiss that lasted 50 hours, 25 minutes, and one second, according to Guinness World Records.
A pair in their 70s who've been married for 50 years, Pannajet and Suwanna Yomjinda, are the oldest couple attending the annual Ripley's Believe It Or Not! contest in Pattaya, Thailand, ITN News reported.
"I'm not sure if we'll win because of our age," Suwanna Yomjinda said to ITN News, "but if we were younger, we would surely win."
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.
