Best man faints while standing beside couple taking their wedding vows (video)

A wedding took an unexpected turn when the best man passed out while the couple were yaking their vows.

Drayton Williams, 28, was at his best friend’s wedding ceremony in Austin, Texas, on Sunday, May 24, when he suddenly collapsed.

About 10 minutes into the outdoor ceremony, Williams fell onto the ground with a loud thud.

As guests gasped in shock, the groom and another groomsman rushed to Williams and helped him back up.

“I had locked my knees,” Williams told Newsflare. “That mixed with being nervous made me feel a bit dizzy, but I just thought it was the nerves in general, not that I was going to pass out. All that said, next thing I know, I was getting picked up by my friends and trying to stand upright after losing consciousness for a split second.”

Locking the knees while standing straight can cause vasovagal syncope, a common type of fainting in which blood pressure and heart rate suddenly drop, because blood may pool in the legs and reduce blood flow to the brain, according to the Mayo Clinic.

Despite Williams temporarily losing consciousness, the officiant didn’t let the medical episode interrupt the ceremony. He quickly glanced at the commotion, then continued his speech as if nothing had happened.

When Williams posted footage of himself passing out a few days after the wedding, the clip went viral with more than 6 million views on TikTok.

Many users commented that the officiant’s unbothered reaction was the funniest part.

“Schedule must’ve been real tight,” one person joked.

Another wrote: “The definition of the show must go on.”
