How do you plan for a substitute teacher?

The dreaded day has finally come!   Tuesday I will be in training all day and will have a substitute teacher.  I hate being out of the classroom not just because I miss my students but also because I hate making sub plans!  I know what it's like to be a substitute teacher in a classroom with poor sub plans.  It is for this reason that my plans take me hours to prepare.  I try to keep the day as normal as possible.  I purchased Amanda Nickerson's Sub Tub.  This has been a life saver for getting things ready!
Do you do any special preparations for having a substitute teacher in your classroom?  How do you encourage your students to behave for the sub?
