I guess they breathed through their nose.

There's nothing more romantic than embracing your loved one on Valentine's Day. But for seven Thai couples entering a kissathon in Pattaya beach in southeastern Thailand on Sunday, it was more of a face off than a bout of romance.
In the end, a same-sex couple secured victory with a kiss lasting 50 hours, 25 minutes and one extra second for good measure.
Nontawat Jaroengsornsinpose and Thanakorn Sittiamthong beat the previous world record holders, whose kiss lasted 46 hours, 24 minutes and nine seconds, according to the Telegraph.
And the prize for the two-day smooch? A $3,300 diamond wedding ring and a $6,600 hotel voucher, notes ITN.
The rules were certainly not for the faint hearted. Couples had to be touching each other at all times and to stay within a one meter square box, explains MSNBC.
If that's not enough, a referee even had to accompany them to the bathroom to ensure they embraced one another while relieving themselves.
