If your spouse ever accuses you of infidelity, Czech sexologists say, you should deny it, deny it, deny it. Even if you're caught in the act, they say, you should still deny it.

The recent Czech version of Clinton's defense has been, "We did not offer a bribe to that man." That man, of course, is MP Zdeněk Kořistka, and "we" is ODS. Mirek Topolánek sent his envoys to talk to Kořistka about bringing down the Gross cabinet, and there's speculation that Kořistka is part of a scheme to discredit the ODS chairman. Topolánek has already been dragged into a debate about just what a "bribe" is.
