How do you get the dry boogers out if you don’t pick your nose? - sh.itjust.works

I always get dry boogers and they’re impossible to remove when blowing into a tissue.

I do not really judge people for enjoying their childhood toys, but back when my son was a lot younger, he really enjoyed watching youtube movies of adults playing with Thomas the Tank Engine toys. Now that was creepy. Also, the fact that people are actively monetizing this felt a bit dystopian.
