I found some nice geeky jokes here. Some of my favorites
* Roses are #FF0000 , Violets are #0000FF , All my base belongs to you
* The box said 'Requires Windows 95 or better'. So I installed LINUX
* Bad command or file name! Go stand in the corner
* Warning! Buffer overflow, close the tumbler !
* Best file compression around: "rm *.*" = 100% compression
* My new car runs at 56Kbps
* Why doesn't DOS ever say "EXCELLENT command or filename!"
