Bride-to-be Sharon Price and fiance Andy Price were left unconscious after their attempt to recreate the famous film spectacularly flopped.
They have both watched the 80s moves over 30 times and wanted to do the famous lift moment on the Big Day.
After larking around in a pub beer garden with the couple thought it would be a laugh if they tried a practice.
But things went disastrously wrong when they collided and Andy, 51, was knocked out cold and they were both pictured sprawled out on the floor.
Sharon, 52, was also bruised and both were rushed to a nearby hospital after the relatives they were with realised they weren't joking.
The couple had been enjoying the sunshine in Weston-Super-Mare, Somerset, when they were inspired to recreate the scene from the 1987 movie.
Just like Jennifer Grey leaping into the arms of Patrick Swayze, Sharon ran at Andy ready for him to lift her above his head.
But instead the couple ended up flat out on the grass.
Sharon was unable to breathe after winding herself, and Andy hit his head so hard he was knocked out.
At first their family thought they were playing - but then dialled 999.
Sharon said: "I have always loved Dirty Dancing and it is one of my all time favourite films.
"We were in the beer garden and my niece and nephew were messing around trying to do the lift.
"So I looked at Andy and suggested that we have it as our first dance at our wedding.
"We immediately set about trying to recreate that iconic moment. Bu it's fair to say it didn't go to plan.
"When I ran at Andy he tried to lift me, but we just collided.
"At first our family thought we were just messing about but they soon realised we had actually really hurt ourselves."
Paramedics loaded Andy into an ambulance after cutting off his t-shirt, and switched on the blue lights as they rushed him to Southmead Hospital in Bristol.
Sharon said doctors at the hospital laughed when she told them how the accident happened.
She said: "The paramedics were pretty worried about Andy and cut his t shirt off and blue-lighted him up to Southmead Hospital.
"We are OK now but Andy has a bruised back and neck and my back still hurts."
The couple, who have been together for 18 months, met while working at Seetru Engineering in Bristol.
Andy got down on one knee after Christmas Day lunch last year and popped the question.
The couple, who are both grandparents, are going to tie the knot next year.
Sharon added: "All I could hear was the paramedics saying he was going in and out of consciousness. Our feet were still entwined and they had to separate us.
"We were both badly bruised but we're alright now.
"I think we're going to go for a slow one for our first dance."
Andy's niece Kerri, 21, who took the photos, said: "We didn't know how serious it was until we saw them on the floor."
