<p><br /> US Vice President Joe Biden has had to convince a sceptical Jay Leno that America did not get a raw deal from Russia in the biggest spy swap since the Cold War.<br /> </p><p><br /> Leno asked Biden during a taping of NBC's "The Tonight Show" why the US was sending 10 accused spies back to Russia while getting only four in return.<br /> </p><p><br /> "That doesn't seem fair," Leno said.<br /> </p><p><br /> "We got back four really good ones," Biden reassured Leno. "And the ten, they'd been here a long time, but they hadn't done much."<br /> </p><p><br /> Leno then showed a sultry photo of alleged Russian agent Anna Chapman and asked "do we have any spies that hot?" The image he showed was taken from a Facebook page and depicts a woman that journalists have identified as Chapman.<br /> </p><p><br /> Biden's reply, in a mock-serious tone said "let me be clear. It wasn't my idea to send her back."<br /> </p><p><br /> The spy exchange took place on Friday on airport tarmac in Vienna.<br /> </p><p><br /> It was Biden's first appearance on the show since taking office in January 2009. Before becoming vice president, Biden had appeared on "The Tonight Show" several times before.<br /> </p>
