A and B both agree
\n" ); document.write( "If I was telling the truth, then both
\n" ); document.write( "A and B were lying.
\n" ); document.write( "---------------
\n" ); document.write( "But there is no day that both
\n" ); document.write( "A and B are lying, since:
\n" ); document.write( "A is lying on
\n" ); document.write( "Mon, Tues, Wed
\n" ); document.write( "B is lying on
\n" ); document.write( "Thurs, Fri, Sat
\n" ); document.write( "-------------
\n" ); document.write( "Therefore, I must have been lying
\n" ); document.write( "and both A and B were telling the truth
\n" ); document.write( "-------------
\n" ); document.write( "There is only 1 day when both A and B
\n" ); document.write( "are telling the truth, so today
\n" ); document.write( "must be Sunday
\n" ); document.write( "
\n" );
