The three men appear to have made the conscious decision to enter the large machine, and later had to be rescued from within it, presumably feeling very silly.
The Essex County Fire and Rescue Service (ECFRS) turned up to the abandoned laundry site in Bower Hill, Epping, at about 6.35am to find the three men, who are believed to be in their late teens, stuck inside the big dryer.
Two of the men had managed to get inside the dryer, but one had managed to become stuck while only partially inside.
The fire brigade reported that his 'ankles became trapped in the door when he tried to crawl in'.
It actually turned into quite a big operation - certainly for something that was completely avoidable - as the fire service had to enlist help from Essex Police, the Helicopter Medical Emergency Service (HMES) and the Ambulance Service's Hazardous Area Response Team (HART).
All for a group of lads who decided it would be fun to get inside a large and potentially dangerous machine inside an abandoned building.
The emergency responders used a number of pieces of heavy equipment and had to actually help the third man who had become stuck to get fully inside before taking off the door to let everyone out together.
The men were then treated with pain relief and passed over into the care of the ambulance workers.
ECFRS watch manager Glenn Jackson said: "It was a difficult site to access and we had to carry a lot of heavy equipment a large distance from the appliances to the tumble dryer and then use our expertise to free the men safely.
"We used a range of equipment to free the casualty's ankles and allow him to crawl into the tumble dryer.
"The HEMS team gave him pain relief and we then managed to move the door, again using a range of equipment, so the men could crawl out."
It goes without saying, and you shouldn't really need telling this, that you shouldn't go climbing into large and heavy machinery that is old and hasn't been used in ages.
In fact, it's probably a decent rule of thumb to just avoid entering derelict buildings in the first place, as there's usually a reason that they're derelict.
