I'd seen them in Whole Foods and the sign (erroneously) said Cara Cara oranges. And they were orange colored as well. Just small and lemon shaped. Ooo, I thought, that's one of those new strains of fruit you see in these pretentious times. So I bought four, and ate one when I got home. Tasted mighty sour, but I stuck at it for the vitamin C. Was nail-deep in the peel of the second one when I looked at the label and saw "meyer lemon." Definitely one of those classic Mr. Magoo moments.
