Early in my career as a team rep, I was fortunate to hire a young woman who was a wonderful coach. She was also a frustrated theater director, I think. She created the most amazing psyche ups before our swim meets. One of her most ambitious projects was staging a mini Star Wars complete with light sabers, Chewbacca, Princess Leia, and a host of 8 & under Yodas. Her psyche ups amused the parents, delighted the little kids, and caught the imagination and the enthusiasm of the older swimmers.
Most psyche ups aren't so elaborate. The only one I can remember from my days as a swimmer was pretty lame. (Sorry, Bill B.) Of course, I was a rather introverted teen at the time, so perhaps everyone else was wildly enthusiastic about getting in the pool and kicking down the length on our backs...growling--or making whatever noises tigers make. (We were the Glenwood tigers...)
