The washing of the feet

Jesus' last meal on earth was the Passover Seder.
Christians rightfully remember it with the breaking of break and the blessing of wine, but I also enjoy how John tells the story:

Jesus washes the feet of His disciples after which He says:
"Do you realize what I have done for you?
You call me "teacher" and "master," and rightly so, for indeed I am.
If I, therefor, the master and teacher, have washed your feet, you ought to wash one another's feet.
I have given you a model to follow, so that as I have done for you, you should also do."

Happy Easter and Passover
