A helicopter rescue gone awry has produced a video people can't stop laughing at - even though they know they shouldn't.
A 74-year-old woman was injured while hiking up a mountain in Phoenix, Arizona on Tuesday (local time).
When firefighters reached her, they strapped her into a stretcher below the helicopter and took off - and that's where it all went wrong.

Video shows the stretcher begin to spin wildly as the aircraft rises into the air.
It gets faster and faster, whirling in a clockwise direction and presumably causing the injured woman a great deal of motion sickness.
At one point the helicopter pilot seems to reconsider the scheme and halts the ascent, before eventually flying away from the rescue site.
The woman was taken to a trauma centre to be evaluated, where she was found to have suffered no serious effects from the spinning except dizziness and nausea.
Officers later told media a line intended to prevent the stretcher from spinning during a hoist rescue malfunctioned, and similar incidents have happened before.
Fox 10 posted a one-minute clip of the rescue to Twitter, where it was met with equal parts shock and hilarity.
"That spiralled out of control," one witty Twitter user remarked.
"She is now 78," joked another, referring to how many times the woman rotated during the wild ride.
Many said they were "going to hell" for laughing at the video, while others said if they were in the same situation they'd rather be left alone on the mountain.
Some added in music over the video - Nicki Minaj's 'Roman Holiday' was a popular choice.
