Phil Robertson is at it again.

The "Duck Dynasty" patriarch launched into a series of bizarre tirades during the Western Conservative Summit in Denver over the weekend.

At various points he tugged on his beard, vowed to never use a women's restroom and screamed about the Supreme Court's decision last year legalizing same-sex marriage , according to clips posted online by DailyPolitics .

But the strangest moment of all may have been when he offered "proof" of Jesus Christ: the calendar.

"It is 2,016 years since Jesus showed up, right?" he said. "So don't tell me he wasn't here."

He then went on:

"By the way, if your calendar is dated of all the human beings who have ever walked on the Earth, and your calendar is dedicated and predicated to just one of em, evidently something rather large went down back then."

"'How come we say it's 2,016 years, I don't believe in this Jesus stuff,'" he said, mimicking a supposed rival argument. "I said, 'well you're counting time by him dude. Face it!'"

While the calendar year is based loosely on certain assumptions about the birth of Jesus, it also honors a few other deities.

March, for example, is named for Mars, the Roman god of war .

That hasn't stopped the family from repeatedly offering the calendar as "proof" of their faith; last year Si Robertson said anyone who uses the date is acknowledging Jesus Christ .

Theres no such thing as an atheist , Robertson, who is brother to Phil Roberson, told the Christian Post. Im serious, because theres too much documentation. Our calendars are based on Jesus Christ. Whether you believe in him or not, every time you sign your calendar, you add down the days date, youre saying hes here, OK? Thats documented.
