What Does This List Mean?

Today I received a pretty funny e-mail from a choreographer who will be working with the Dancers' Company this coming week. He had a list of things he wanted us to bring to rehearsal on Monday. Please tell me this is as funny as I thought it was.

They will need:
- Knee pads.
- Water bottles and Gatorade or Propel or Powerade (some type of electrolyte/sugar replenishment).
- Sweat towels or hand towels.
- A spiral notebook and pencil for notes.
- A change of clothes in the event of excessive sweating.
- Women should bring ankle length leggings, if they have them. (preferably black)

My personal favorite is the change of clothes in the event of excessive sweating. Really? I can't wait to see what we will be doing tomorrow morning...
