When we think of linux, we think of some serious people and their serious talks. Linux is not that much serious as you think. We came across a funny feature of shell.We tested it on Ubuntu Jaunty Jackalope. Try it in your distro. Its really funny. Whenever we type "sudo " it asks for password. When we type it wrong it simply says the password is wrong.

But when we add one more parameter to the defaults entry, it gives insults on typing the wrong password. Here it is...........

 $sudo visudo
