Blue Ear Wax

Everybody knows you’re not supposed to stick a cotton swab down in your ear canal to dig stuff out, but we all do it anyway.
You gently swirl it around in there, even though eardrums will rip no matter how gentle you are.
The cotton swab comes out and…
It’s blue.
Usually, you can expect some yellow or tan ear-wax, but blue?
What could you have stuck in your ear that was blue?
Why don’t you remember?
Do you dig in there deeper?
Do you call the doctor?
Or…
This is why there’s cotton at either end of the swab.
