I wonder what misconceptions I hold. I help my mom with a lot of them, and it's always interesting to figure out where they came from.
I doubt I'll ever get her to call tortillas tortillas though, she always calls them shells. While that would be accurate for hard shell tacos, she always means the large flour tortillas for burritos, and if I'm not the one buying, she gets hard taco shells and gets mad.
as a kid, I always thought we were related to the Quaker Oats quaker. We're neither Penn's nor quakers, but our family share a lot of those facial features. Turns out he's William Penn, of Pennsylvania.
My Grandpa resembled a thinner version of him, sans hat and wig.
As to etsy, there is some crazy stuff on there, like Frasier 64 for the Nintendo 64. (It's just a label on a random cart)
I'm always checking etsy for an SNES mousepad. I left mine at a cousin's house in 1994, and every time I've found one, it's got kid damage. I want a pristine one.
