Billionaire philanthropist and Microsoft founder Bill Gates had his hands full on-stage in Beijing on Tuesday, showing a jar of human faeces.
Axar.az reports Foreign media that the stunt was part of his speech at the Reinvented Toilet Expo event - a showcase for new toilet technologies.
The Bill & Melinda Gates Foundation has spent more than $200m on researching the field across the last seven years.
Twenty cutting-edge sanitation products were on display, intended to destroy harmful bacteria and prevent disease.
"I have to say, a decade ago I never imagined that I'd know so much about poop," Mr Gates joked at the conference. "And I definitely never thought that Melinda would have to tell me to stop talking about toilets and faecal sludge at the dinner table."
The entrepreneur was helping to launch the three-day event in China - where leader Xi Jinping has made a so-called "toilet revolution" across the country a policy priority.
