During a Friday press conference, Zakharova said she'd make a "lyrical diversion" and read her own adaptation of "My Heart's in the Highlands" by Robert Burns.
"His heart is in Moscow, his heart is not there, his heart is in Moscow, chasing a bear. Chasing not grizzly, but Kremlinese. His heart is in Moscow, wherever John is," Zakharova said.
On a more serious note, Zakharova said the frequent phone calls and visits between Kerry and Russian Foreign Minister Sergei Lavrov show that problems in international relations cannot be solved without Russia's participation.
"As we now can see global problems can only be solved with participation of the Russian Federation," the spokeswoman said.
Just a few days ago Kerry phoned Lavrov to discuss the Syrian ceasefire.
A ceasefire hammered out by Russia and the United States has been in place in parts of Syria since late February. UN Special Envoy for Syria Staffan de Mistura said last week that the truce was barely holding and urged the two powers to save the peace process.
