In the library, young Johnny Munch is writing Helen's name with his left hand, but later (and in other episodes) we see that Munch is actually right handed.
Kellerman: High school hasn't changed that much since I graduated.
Munch: When was that, about two years ago.
Kellerman: Haha, it was 1984.
Munch: "The only thing I have in common with Judaism is we both don't like to work on Saturdays."
Munch: What happens to us that we forget how wonderful it is just to hold another human being's hand?
Kellerman: We get older.
Munch: We get older. We forget who we used to be, what we used to believe in. Love, peace, the Colts would always be in Baltimore...
Munch: Come on, do it for me just one more time, please, and I won't ask you again.
Kellerman: Would you give it a rest?
Munch: Just once more, please?
Kellerman: Oy vey iz mir, I'm so meshugenah I could plotz.
Munch: Do it again.

Title: Kaddish is the name for a number of Jewish rituals praising the name of God. The most familiar form is the rite for the dead, the Mourner's Kaddish, which is evidently the one referred to here. On the death of a relative or spouse, it is recited daily for thirty days and on the anniversary of death (for a parent, it is performed daily for eleven months).
