Throughout the The Hitch-Hiker's Guide to the Galaxy (or however you wish to hyphenate it) novels we are never told the question, you know, the Ultimate question to life the Uinverse and everything.

As a consolation prize we are told God's last message to his creation. It is read to Marvin by Arthur Dent and simply says "We apologize for any inconvenience"

Marvin by this time is thirty-seven times the age of the universe due to a bad reckoning with a time machine or two. Upon hearing this message I believe that Marvin says something along the lines of liking that. Then he dies.

I have always felt that this message was for Marvin alone, after all he had gone through. It made me glad that in the end he at least found peace.
