Even the way he catches Tommy Brown at the end was still very classy, up on that mountain and all. However, one of his most un-characteristic captures occurs at the end of Rest In Peace, Mrs. Columbo when Vivian Dimitri slaps him in the face.
Technically, Roger Stanford of "Short Fuse" slaps him in the face too, though totally different from "Rest in Peace, Mrs. Columbo." The guy is totally relieved.
