Oil Magic - Just For Laugh

Wife calls husband in his office. Wife: Window is not opening. What shall I do? Husband: Put some oil and wait for while. It will open. If not, then put more oil and wait. Wife (little unconvinced) : Are you sure? Husband: Yes, trust me, it will do the magic. Try it. After a while, husband calls back to check: Did you do as I told you? Did it do the needful trick? Wife: I don't know about the trick or magic, but now the entire laptop is not starting.
