I heard a familiar voice.
"Wait a minute, Evie, that's Ducky!"
If you watch NCIS, then you know Ducky is Dr. Donald "Ducky" Mallard, the Chief Medical Examiner played by actor David McCallum.
Intrigued I did alittle Wiki lookup and found out not only is he the voice of Paradox on Ben 10 Alien Force but he used to be a little of a sex symbol when he played Russian spy, Illya Kuryakin, on the Man From U.N.C.L.E.
Uh and he also made a record called "The Edge" that was sampled by Dr. Dre for "The Next Episode" (One of my favorite Dre songs)
Bonus cool points!
