Useless info about Metallica finally becomes useful

Do you have useless infomation rolling around in your brain too? Mine is usually about rock bands. How often does the fact that Brian Johnson (AC/DC) wrote 'Thunderstruck' while on a plane in a thunderstorm come up in conversation. I'll tell ya, zero. This Metallica fan managed to make his love for the band work for him on the British tv show Mastermind, kinda like our Jeopardy. He nailed 8 out of 10 questions about the band when somehow the category popped up randomly. Impressive. Just goes to show, you shouldn't rely on Google for all your brain power.
