sorry if i'm the one in the wrong here, but i think the 42 stands for :
"Many occurrences of the number 42 in pop culture can be attributed as an homage to Douglas Adams' book The Hitchhiker's Guide to the Galaxy, in which the number 42 is The Answer to the Ultimate Question of Life, the Universe, and Everything."
As I've heard him say "So long and thanks for the fish" on more than one occasion, I would be inclined to think that he was referring to the Hitchhiker's Guide as well
