Many years ago I played drums in a band, and often the guitar players would write weird little off time parts that I couldn't do at first, but I could the next day. I used to tell them that I would practice in my sleep. The first time I said it I was ridiculed, but when I nailed the part it became a running joke that I should bring a bed to the practice space.
