Paul, a potential 2016 presidential candidate, unleashed a string of cranky Festivus-themed tweets on Monday. Former Seinfeld writer Dan O'Keefe thinks the reference is rather dated.

"When Rand Paul tries to seem relevant with 15-year-old pop cultural references, it reminds me of when Bob Hope used to dress up as the Fonz, but that’s just me," O'Keefe said on CNN Tuesday.

Paul's "airing of grievances" included tweets attacking Senate Democrats: ("If you want more bipartisan cooperation, talk more not less") and personal grievances ("I can never remember when to move my car for DC street cleaning").
