Wife calls husband in his office.!!!

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.
