Prince Charles and the Duchess of Cornwall had trouble maintaining their composure when they kicked off their royal tour in Canada, which coincides with the Canada 150 festivities.
The couple couldn't help but chuckle during a traditional welcoming ceremony in Iqaluit, which included a performance by indigenous throat singers.
Prince Charles and Camilla were filmed struggling to hide their grins at the recital.
The prince also met with groups who work to promote and preserve the Inuit language.
"Each time I visit Canada, I see the strength and resilience of the people who live here," Prince Charles said.
"The importance of their indigenous traditions and the vision and drive that helped shape this extraordinary nation.
"I pray that the celebration of 150 years of Confederation will encourage all Canadians not just to look back with pride, but also to look forward with hope and inspiration."
Prince Charles made no comment about finding the throat singing so funny.
