O'Sullivan 

The third most common name in Ireland.

the O'Sullivan family line once ruled county cork, until the notorious potato famine, many of the O'Sullivan family emigrated to Manchester for a better life, although just how many and exactly when is a mystery.
As with any name starting with O followed by an apostrophe, it means 'Brother of' or even 'Slave of' So the original O'Sullivans would most likely have been freed slaves or nameless families who where accepted by the Sullivan family as their own for great deeds or services rendered.

Famous O'Sullivans include Ronnie O'Sullivan (snooker player) and Richard O'Sullivan(1960's actor, Robins nest)

They are generally prolific breeders and have been known to father children out of wedlock, or simply deny the existence of an offspring/sibling for reasons known only to themselves, Also notable is an inherent tolerance for alcohol, probably stemming from Irish roots, most O'Sullivans enjoy Guinness, however, this is not as common any more, most will just drink until their vision is impaired and their legs unable to transport them directly to their destination and yet somehow wake up right as rain.

What is your name?

Mr O'Sullivan.

OH do you know Ronnie?

sigh.

O’Sullivan’s Law 

O’Sullivan’s Law states that any organization or enterprise that is not expressly right wing will become left wing over time. The law is named after British journalist John O’Sullivan.

Television shows are the best examples of this. 24, House. Charitable foundations are worse but harder to see.

One of the reasons for this is leftist intolerance versus right-wing tolerance. Right wingers are willing to hire openly left-wing employees in the interest of fairness. Left-wingers, utterly intolerant, will not allow a non-Liberal near them, and will harass them at every opportunity. The result over time is that conservative enterprises are infiltrated by leftists but leftist enterprises remain the same or get worse.

Also, leftism is in and of itself a form of decay. It’s what happens not just to television shows but to nations, churches and universities as the energy given off by the big bang of their inception slowly ebbs away. Rather than expend vitality in originality and creation they become obsessed with introspection, popularity and lethargy. Leftism is entropy of the spirit and intellect.

Another reason is that the parasitic nature of Liberals/Leftists attracts them to existing money.

An enterprise can stave off O'Sullivan's Law if their creators keep it in mind and remain vigilant and truthful.

O'Sullivan's Law hit 24 when they finally had a Muslim villain then started running disclaimers that Muslims aren't all terrorists.

The Annenberg Foundation was started by a Republican but it didn't take long before O'Sullivan's Law had them handing a domestic terrorist money for educating kids.

The ACLU, the Ford Foundation and the Episcopal Church all fell to O’Sullivan’s Law.

Randy O'Sullivan 

"The Randy O'Sullivan"

It is a sexual act involving one man and women. It refers to a baseball pitcher that had a legendary pitch. The act itself simply involves the man cumming into his hand and like the "Spiderman" move, throwing it at the women. However the throw is done in the form of a baseball pitcher and as it's being done you shout - Randy O'Sullivan!

"Mate last night was so funny"
"Why's that?"

"I Randy O'Sullivaned my girlfriend!"
"Haha nice one lad!"
