Naming after Thule, a mythical region in Scandinavia
Discovery and first isolation Per Teodor Cleve (1879)
My Thulium dissolved into a dilute sulfuric acid last night, While I was studying the 69 electrons surrounding the nucleus.

It's not just any number....
It's a sexual intercourse position where one(mostly male) licks the female vagina and the other one (mostly female) sucks the male dick for pleasure while female being on top of male or vice-versa.
It's often used to slip into conversations to hint about sexual intercourse.
Male: I guess it'll be 69 today (hinting)
Female : (blushes) I guess so
Let's do it 69. I like it
