I was thinking that! When I was a kid I had a mole on my neck that looked similar in size and color to a tick. At least once a year someone would try to "catch it"
Luckily more often it was serious looks and warning there was a tick on me.
In fairness, I was in the woods a lot and had to check for ticks on the regular.
But yeah, my grandma for sure would have whacked me upside the head if she saw that spider earring.
