Long time followers of Senator Rand Paul's twitter feed know that the sometimes offbeat Kentucky Republican makes a big deal out of the fictional holiday Festivus, which was popularized by the telveision Sitcom "Seinfeld."

Last year, Paul celebrated Festivus with an election-themed airing of grievances against his fellow Republican presidential candidates.
