Silly nerd pride thing: I had the Wikipedia entry for an element open. I wanted to go to a different specific element. I scrolled up to the little clickable "periodic table with no labels" in the infobox, went "it should be somewhere about….. there." and clicked. Got it right. Note: I don't know the periodic table well enough to have known for sure. I just intuited and clicked. And no, it wasn't an obvious one like H or a noble gas.
