Some funny jokes... "Dating a girl is just like writing software. Everything's going to work just fine in the testing lab (dating), but as soon as you have contract with a customer (marriage), then your program (life) is going to be facing new situations you never expected. You.ll be forced to patch the code (admit you're wrong) and then the code (wife) will just end up all bloated and unmaintainable in the end."
"Once upon a time there was a DOS user who saw Unix, and saw that it was good. After typing cp on his DOS machine at home, he downloaded GNU's unix tools ported to DOS and installed them. He rm'd, cp'd, and mv'd happily for many days, and upon finding elvis, he vi'd and was happy. After a long day at work (on a Unix box) he came home, started editing a file, and couldn't figure out why he couldn't suspend vi (w/ ctrl-z) to do a compile."
