Great story.
I was a huge HHGTTG fan (counting Disaster Area among my top musical influences)
When I was at UWO in the early 90's Douglas Adams came on campus for a book signing - it was to last about 45 minutes, and it was scheduled right in the middle of one of my exams.
So I decided to sit the exam, thinking "I'll catch up with him at a future book signing", alas he died before I ever got the chance.
