The Ultimate Answer to the Ultimate Question of Life, the Universe and Everything. But don't you dare go looking for the question. If you find it, the universe will be replaced with something even stranger. And that might not necessarily be a good thing. Of course, some say that this has already happened. Also, 24 reversed. (The Doctor Who episode named "42" was a reference to this, since it took place in Real Time over 42 minutes.)

Also the number of lines per page in the Gutenberg Bible. And it is part of a string of lottery numbers that add up to 108. 101010 in binary (which also happens to be the date that Friendship Is Magic's pilot aired). 52 in octal. 2A in hexadecimal. 10 in base 42. Six times nine in base 13. 42 plus 4 plus 23 equals 69. And 2 plus 3 is 42. Major League Baseball teams occasionally retire a number worn by one of their legendary athletes. The New York Yankees, for example, have retired the number 3 (worn by Babe Ruth) and 4 (worn by Lou Gehrig). 42 (worn by Jackie Robinson) is the only number to be retired not by one team, but by every single team in the National League — and, later, by every team in both leagues. 42 is the title of the biopic about Robinson.
