Welcome to the Red Bull Soapbox race, where teams of wildly excited adults build a wonderfully bizarre range of carts, and send themselves hurtling down a steep downhill course.
Achieving speeds of up to 45 mph, these carts are propelled by nothing more than gravity and steely determination as they manoeuvre their way around a range of jumps and obstacles, often losing control and crashing hilariously along the way.
This year's Soapbox race was held on the slopes surrounding London's Alexandra Palace, and I went along to see just what this wacky race involved.
Many of the carts were modelled after popular culture icons, such as this landspeeder from 'Star Wars'.
As a race, it's important for each team to set the fastest time possible in their run down the 500-metre track, but points are also awarded for the creativity in the design of the cart, the costumes, and the flair of the 20-second performance each team must perform at the start of their race.
I asked them if they were at all concerned about the dragon-mother Daenerys Targaryen chasing down the throne aboard her dragons. "Red Bull clocked us at 38 kph and I have it on good authority that Daenerys' dragons can't fly much faster than 30 kph, so she isn't going to get it back," the king confidently explained.
The Steampunked Mean Machine picked up a lot of speed on its run. As you can see, its crossing of the finish line was somewhat dramatic.
"The brakes were always an issue," Moore explained, "When Craig (the driver) got to the bottom he tried to 'Tokyo drift' it round to slow it down but the back wheel ended up buckling and sent him upside down. He's fine and survived. Just a couple of bruises and scrapes."
The winning team, 'The Breakfast Club' wowed the audience with a car that started the race as the A-Team's iconic black van, before shedding its bodywork to become the 'Dukes of Hazzard's Dodge Challenger, before finally turning into the DeLorean from 'Back to the Future'.
It may not have hit 88 mph going over the jump, but the flame effect was a winner nonetheless.
Team 'Turtleheads' modelled their racer after Crush from 'Finding Nemo.' Team members Kevin and Sam told me it took them a full 10 weeks to build. "There's a quiet road behind our garage that we had our test runs on. Luckily the road was empty because during our first test the steering wheel snapped off and we had a big bump into the wall."
"Taking part felt surreal," they told me. "Nothing will ever compare to it, the crowd really got behind us and it left us speechless."
"We had the best weekend we could have hoped for, so many teams were great sports and fun to be around, the staff were all amazing. To top it off we even managed to snag the people's choice award and spray a little champagne."
The bales of hay were so fresh, I managed to find this tiny baby field mouse inside one. It wandered precariously close to the track so I scooped it up to find it a better, much safer home in the nearby woods.
