From a Mental Floss article about the selection of the Canadian flag in 1965, the flag pictured above was the preferred flag of then Prime Minister Lester Pearson but proved unpopular with pretty much everyone else. This burn from an Albertan youngster is priceless:

“I don’t like the three maple leaves on the white background… the single maple leaf looks better. As I am only 10 [I] will have to look at it longer than Mr. Pearson.”
