NCIS and U.N.C.L.E.

In last night's episode of NCIS, the team acts to protect Ducky (David McCallum), the next target in a series of killings linked to a years-old trial. At one point, Agent Todd (Sasha Alexander) asks Gibbs, "What did Ducky look like when he was younger?"

Gibbs thinks it over, and answers, "Illya Kuryakin," the character McCallum played on The Man from U.N.C.L.E.
