This Holiday is celebrated by altering your own consciousness in any way that is permissible to your superego and repeating the following affirmation 666 times:
Sri Syadasti Syadavaktavya Syadasti Syannasti Syadasti Cavaktavyasca Syadasti Syannasti Syadavatavyasca Syadasti Syannasti Syadavaktavyasca
In the alternative, some prefer a chant:
Unlike a song, chants are not sung but chanted. This particular one is much enhanced by the use of a Leader to chant the Sanskrit alone, with all participants chanting the English. It also behooves one to be in a quiet frame of mind and to be sitting in a still position, perhaps The Buttercup Position. It also helps if one is absolutely zonked out of his gourd.
RUB-A-DUB-DUB O! Hail Eris. Blessed St. Hung Mung. SYA-DASTI O! Hail Eris. Blessed St. Mo-jo. SYA-DAVAK-TAVYA O! Hail Eris. Blessed St. Zara-thud. SYA-DASTI SYA-NASTI O! Hail Eris.

It is then repeated indefinitely, or for the first two thousand miles, which ever comes first.
