Yes, covering all bases is important! Last year I had to learn that. We should write a story and using as many as possible song titles by the Wise Guys for it. The winner got a ticket for a special concert. Out of 164 songs I used 156. The rest I thought was not possible, since some were double, just old and new versions or German and English versions. So I thought one of each version would be sufficient.

Still, there was somebody who really used ALL of them and in the end I only made fifth place. I still was able to go, though, luckily the father of my friend didn't want to and so I got his ticket ;)
