At least he did according to this article apparently attributed to a joke from Polands Foreign Minister :

A political scandal is gathering pace in Poland. Officials of the Polish administration are accused of releasing racist statements against US President-elect Barack Obama. Poland’s large opposition party Right and Justice said that the remarks had been voiced by the Polish Foreign Affairs Minister Radoslaw Sikorski, the Dziennik newspaper wrote. Why does Barack Obama have Polish roots? Because his grandfather ate a Polish missionary

“Why does Barack Obama have Polish roots? Because his grandfather ate a Polish missionary.” This is the joke that Sikorski supposedly distributed in his ministry. The minister, the newspaper wrote, explained afterwards that he had heard the joke from someone else. However, Witold Waszczykowski a spokesman for the National Security Bureau, confirmed that he had heard the joke from Sikorski and added that he would be ready to testify at court.

The head of another opposition party of Poland, The Union of Leftist Democrats, Wojciech Olejniczak, said that he had heard Jaroslaw Kaczynski, the chairman of Right and Justice, telling the same joke, Newsru.us says.

In addition, Artur Gurski, a spokesman for Right and Justice, stated last week at the Polish parliament that the election of Barack Obama would “mark the end of the white man civilization.” Spokespeople for the Social and Democratic Party of Poland filed a legal complaint in connection with Gurski’s racist remarks, which, as they said, dishonored the Polish administration. If convicted, the deputy can be sentenced to up to three years in prison.

They do take their politics seriously in Poland it seems.
