Google Talk about信息中的神秘数字

我瞎猜的哈，呵呵，下午吉子跟我说你看Google Talk的about信息最下面一行有一排暗灰色的数字，很是好奇，难道是你的身份证号码？银行密码？
后来问吉子，好像大家的数字都是相同的，就是
23 21 13 16 21 19 7 1 13 5
觉得很是奇怪，好像是有种规律。
最初以为是类似于数字规律的这种东西，后来怎么弄都没又规律，于是觉得很有可能是密码。字符？音符？看着最小的是1，最大的是23，没有超过26（字符个数），很有很能是字符，如果1是a的话，7是g，难道是gmail，于是翻译了一下，发现是
23 21 13 16 21 19 7 1 13 5
w u m p u s g a m e
这是个什么东西啊，不解啊。于是在Google Talk的界面上找线索，添加了wumpusgame@gmail.com为联系人，以为会出个机器人啥的，结果没有……
试了半天，只好上网Google了，提示我是否是搜索Wumpus Game，是，才知道Wumpus是计算机上很重要的也是很早的计算机游戏，……
在Wikipedia上发现：
Hunt the Wumpus was an important early computer game. It was based on a simple hide-and-seek format, featuring a mysterious monster (the Wumpus) that lurked deep inside a network of rooms. Using a command line text interface, the player would enter commands to move through the rooms, or shoot arrows along crooked paths through several adjoining rooms. There were twenty rooms, each connecting to three others, arranged like the vertices of a dodecahedron (or the faces of an icosahedron). Hazards included bottomless pits, super bats (which would drop the player in a random location) and the Wumpus itself. When the player had deduced from hints which chamber the Wumpus was in without entering it, he would fire an arrow into the Wumpus’ chamber to slay it. However, firing the arrow into the wrong chamber would startle the Wumpus, which might then devour the player.
不过这些不重要，重要的是最后几句话：
There is a version of Hunt the Wumpus found in Google Talk. Add wumpus.game@gmail.com to your buddy list and send it a text message of “play” to play.

我加了，不过不在线啊，哈哈哈哈哈，有意思！
