I have fond childhood memories of eating frozen treats during heat waves in southern Ontario when I was a kid. One was vanilla ice cream that came in a thin plastic cone. The store clerk would give you a small wooden spoon and the ice cream was delicious. When you got to the bottom of the cone there was a ball of bubble gum. The other was a frozen fruit ice that came in a foil wrapper shaped like a tetrahedron. I think it was called Lola but I can't find it with Google. I have a vague memory of noticing the Beatles eating Lola's in Help!
