For science, I wrote a SEDE query to find comments matching a term (e.g. "where", "located", "country", "world") on questions with a given tag (e.g. "electrical"). The intent is for evidence for why we'd put tag tips to good use.
That is a nice benefit of those things. I may just have to invest in one some day.
In college, I recall someone forgetting to pay his gravity bill. The utility crew came by while they were in class, shut off the gravity, left a note on the white board, and when they opened the door they found everything stuck to the ceiling. Good thing they had a ceiling.
