TV chef Jamie Oliver has been out and about in a fat suit to show the dangers of eating too much junk food.
He was filming a trailer for his new show, and was seen carrying a pile of burgers and chips. In one scene his scooter collapsed beneath his bulk!
The one-off show follows the progress of his high-profile campaign to improve food in schools.
In the past Jamie has criticised the government's efforts to get kids to ditch junk food and eat more healthily.
Although Jamie met Prime Minister Tony Blair to tell him about his concerns over kids' diets, he has said politicians are working too slowly to change food standards.
However, the government says it has set out a clear plan for bringing in the changes it's promised.
That includes banning junk food from school meals and vending machines.
