O.J. Simpson turned 72 on Tuesday, dubbing it his “33rd annual 39th birthday.”

The Juice celebrated in the only way he knows how — with a round of golf and an off-the-rails Twitter video, in which he spoke about sports, his “haters” on the internet and cable TV, ancient Greek Philosophers, race relations in America today and the “hurricanes” that have descended upon his life.

At one point, Simpson called out former NFL quarterback Colin Kaepernick for complaining about the flag-inspired Nike shoe design that was pulled from shelves recently.

“Lately, I saw what Kaepernick pointed out — that the Betsy Ross flag was being used by some negative groups as their symbol,” Simpson said, sporting an all-black Nike golf shirt and clutching one of his clubs.

“Well, I say don’t let the negative win,” he added. “As far as I’m concerned, that flag represents the birth of America.”

Simpson appeared to start the video off with a golf drive before turning his attention to the camera.

“That’s what I’m talking about!” he said. “This is yours truly…Today I am celebrating my 33rd annual 39th birthday, and I gotta tell you, it’s been quite a ride. They say in every life some rain must fall — well, I’ve had some hurricanes descend in my life. But I thank the Lord because through it all, He’s kept me relatively healthy and in good spirits and positive. And that’s tough to do today with all the haters on the internet and on cable TV — spouting their negative opinions on just about everything.”

Still clutching his club, the USC legend and Heisman Trophy winner continued: “You know I like — was it Plato or was it Socrates, who said about opinions that they are not fact. That at the most they could be a possibility and maybe even a probability. But the facts are, they are not facts.”

Simpson, who was famously acquitted of murder in the 1990s, went on to say that “a lot of good things” had happened in his “39 years” — including improved race relations. He described seeing a softball game on at a bar one day, in which Alabama and Texas were playing each other and both teams had black athletes.

“The pitcher for Alabama was black and the lead-off for Texas was black,” Simpson remembered. “I said, ‘Now that’s something to celebrate.’ Because when I was in school, those schools didn’t allow blacks to play in any sport.”

Simpson has been using Twitter for more than a month now and has been regularly posting videos. He concluded Tuesday’s clip with a jab at his golf buddies.

“I got some guys to beat and some cake to eat,” Simpson said. “Take care,”
