I am referred to as a walking arsenal of useless knowledge by more than one person.
My brain houses so many unimportant details, names, dates, situations, etc. that I have very little room leftover for important things.
In a very general sense I can tell you what year literally hundreds of songs by different artists were released and what album they are on. (Modern times, say the last 20 years, not so much). Also for some ridiculous reason every name that I have ever seen flash across a TV screen is etched in my memory. A sitcom from the 70s-80s doesn't exist that I can't tell you the names of the actors. Along with most dramatic series. Pretty much anything I ever watched with any regularity. Need to know who played Rollo on Sanford and Son ? No problem, it was Nathaniel Taylor.
