I went to a Rammstein show, after it me and a friend couldn’t get to the hotel because there weren’t any buses that late, so we went to the back street to wait, might see the band go out or something and we had nothing better to do. At something like 3AM the gates open and they all walk out, we just stayed there because we didn’t want to bother them, but then Till walked towards us and asked “Have you been waiting long?” We were a bit befuddled and answered “yes?” and he said “Sorry to keep you waiting” and took a picture with us.
Not a great story, but as a huge Rammstein fan that was really cool.
I did magic tricks as a hobby, I would practice some card techniques with whatever I had at hand, e.g. credit or parking cards. There are several things you can do with cards or coins that are quick and cool.
