You would think he ought to know by now, but Dave Coulier continues to contradict himself about whether or not former girlfriend Alanis Morissette wrote her popular breakup song, "You Oughta Know," about him.

After admitting to being the subject of Morissette's scathing anthem, the actor who played Uncle Joey in "Full House" now says the song had nothing to do with him.

"First of all, the guy in that song is a real a-hole, so I don't want to be that guy," Coulier, now 54, told Buzzfeed recently. "Secondly, I asked Alanis, 'I'm getting calls by the media and they want to know who this guy is.' And she said, 'Well, you know it could be a bunch of people. But you can say whatever you want.'"

How Dave Coulier Knew Alanis Morissette's 'You Oughta Know' Was About Him

So Coulier, who dated Morissette in 1992, started what he now calls an "urban legend."

"One time, I was doing a red carpet somewhere and [the press] just wore me down and everybody wanted to know so I said, 'Yeah, all right, I'm the guy. There I said it.' So then it became a snowball effect of, 'OH! So you are the guy!'

Coulier's latest comments, however, contradict what he told The Calgary Herald back in 2008.

When he first heard the 1995 song on the radio, he told the newspaper, "I said 'Wow, this girl is angry.' I listened to the song over and over again and I said 'I think I have really hurt this person.'"

The actor also told HuffPost Live last year about the moment he realized that the song, in fact, did strike a chord. "There was a lot of familiar stuff," he said. "But the one that got me was, 'I hate to bug you in the middle of dinner.'"

"We had already broken up," he continued. "She called and I said, 'Hey, you know, I'm right in the middle of dinner. Can I just call you right back?' And so I remembered that line when I heard 'You Oughta Know,' and it was more like, 'Uh-oh.'"

Regardless of whether you believe him now or then, Coulier maintains there are no hard feelings between the two exes.

"I like to think that we parted as good friends," he told HuffPost Live. "I think nothing but the world of her. I think she's a pretty outstanding human being to be quite honest."
