Media Matters for America has long documented Fox News Host Bill O'Reilly's ongoing fascination with what he sees as a causal link between marriage equality and inter-species marriages. Yesterday, he made yet another reference on his show, The O'Reilly Factor. Speaking to guest Margaret Hoover, he said:

O'Reilly: Hoover, you would let everybody get married who want to get married. You want to marry a turtle, you can.

You can watch the segment below:

Back in 2005, Media Matters had taken notice of similar commentary from O'Reilly, but then it was goats. From the March 29, 2005, edition of The Radio Factor:

O'Reilly: The judges in Massachusetts knew they weren't going to be impeached when they said to the state legislature, "Gay marriage is now legal in Massachusetts because we say it is. We the judges" -- they knew they weren't gonna be impeached. They knew the legislature didn't care. You get the government you deserve. In California, the prevailing wisdom is marijuana is no big deal, let's legalize it. And since we can't get that through the legislature, we'll do it this way. And they did it! You see?

And 10 years, this is gonna be a totally different country than it is right now. Laws that you think are in stone -- they're gonna evaporate, man. You'll be able to marry a goat -- you mark my words!

A few weeks later, O'Reilly continued with his goat fixation on the April 13, 2005, edition of The Radio Factor:

Now, there was another request up there from a woman -- prisoner, inmate, convict -- who wanted to marry another woman who's not in prison. And, I guess they're still mullin' that over. No, it was denied -- no, I'm sorry, they're mullin' it over -- no, it was approved! Oooh, no, look at this! The other request was approved because it involved the marriage of a female inmate to a woman who's not in prison. See, I woulda denied that. I'd have said, "When you get outta prison, you can marry her." But not here. This isn't pre-Cana [Catholic premarital counseling] prison -- all right, you can't do that. See, I'm not buyin' into any of this politically correct nonsense. If you're a prisoner, you're a convict, you lose your rights until you get out. So, I'm sorry. We're not lettin' you get married, not gonna let you drive a car, you can't vote. You're in -- you're in, that's it.

So this is just the beginning, ladies and gentlemen, of this crazy gay marriage insanity -- is gonna lead to all kinds of things like this. Courts are gonna be clogged. Every nut in the world is gonna -- somebody's gonna come in and say, "I wanna marry the goat." You'll see it; I guarantee you'll see it.

By the September 14, 2005, edition of his radio show, O'Reilly had moved on to ducks:

The secular progressive movement would like to have marriage abolished, in my opinion. They don't want it, because it is not diverse enough. You know, that's what this gay marriage thing is all about. But now, you know, the poly-amorphous marriage, whatever they call it, you can marry 18 people, you can marry a duck...

One of the arguments against gay marriage, that we just spoke about, is that if it becomes law, all other alternative marital visions will be allowed. We've already seen a Dutchman marry two ladies in the Netherlands. Looks like a happy guy. And now comes word that a British woman has married a dolphin in Israel. Forty-one-year-old Sharon Tendler has tied the knot with a 35-year-old mammal, so age is no problem there.

According to an Associated Press report, Tendler's "marriage" was not a legal one. She reportedly "still kept open the option of 'marrying human' at some stage," but, "she said for now she was strictly a 'one-dolphin woman,' " and that she "hope[s] he has a lot of baby dolphins with the other dolphins. The more dolphins the better."

Also, the Dutchman O'Reilly referred to was also not legally married according to sources who actually researched the case. For facts and more information on marriage equality, please head over to www.FreedomToMarry.org and read through GLAAD's Talking About series.
