Rand Paul has a lot of grievances to share with us.

The GOP presidential candidate on Wednesday again celebrated the comic "holiday" of Festivus, made famous by a 1997 episode of Seinfeld, by launching the traditional "airing of grievances" on Twitter.

"I've got a lot of problems with you people and now you're gonna hear about them!" #Festivus — Dr. Rand Paul (@RandPaul) December 23, 2015

Paul performed a similar tweet storm on December 23, 2014. But this time, he launched some zingers at his presidential rivals.

He took aim at Donald Trump's recent use of the Yiddish-derived word "schlonged," which the GOP frontrunner insists is not "vulgar."

Where to start but @realDonaldTrump. If u bring the Yiddish, know what it means. Guess that's more of a kvetch than a grievance #Festivus — Dr. Rand Paul (@RandPaul) December 23, 2015

He poked fun at Ted Cruz's birthplace in Canada.

My friend @tedcruz has still not pledged to issue exec order declaring Canadian "bacon" is not real bacon. Makes me suspicious. #Festivus — Dr. Rand Paul (@RandPaul) December 23, 2015

He mused about Ben Carson's low-key style in the debates.

I have no grievances against my fellow doc @RealBenCarson because I have not heard a word he has said in any debate. #Festivus — Dr. Rand Paul (@RandPaul) December 23, 2015

... and he didn't have particularly kind words for Jeb Bush's performance in the debates, either.

.@JebBush is always trying to change the debate rules to allow extra time for awkward pauses in answers. Not gonna happen. #Festivus — Dr. Rand Paul (@RandPaul) December 23, 2015

He dinged Marco Rubio's low attendance rate in the Senate.

to my absentee friend @marcorubio, I didn't put your $170k+ salary in my waste report today. But I could have #Festivus — Dr. Rand Paul (@RandPaul) December 23, 2015

And he even weighed in on Hillary Clinton's delayed reappearance from the restroom during Saturday's Democratic debate.
