The longest kiss ever recorded lasted 58 hours and 35 minutes. This record was achieved by Thai couple Ekkachai and Laksana Tiranarat in 2013 at an event organized by Ripley's Believe It or Not! in Pattaya, Thailand. Their kiss began on February 12th and ended on Valentine's Day, two days later.
However, it's important to note that the Guinness World Record for the longest kiss has since been deactivated. Guinness World Records explained that the record was discontinued due to safety concerns and the potential for participants to suffer health problems.
While the couple's dedication to the challenge is impressive, it's important to remember that attempting to break this record is not recommended.
