lie -clock

A man died and went to heaven. He saw a huge wall of clocks behind him. He asked the angel, 'What are all those clocks?'

Angel answered, 'Those are Lie-Clocks. Everyone on Earth has a
Lie-Clock. Every time you lie the hands on your clock will move.'

'Oh,' said the man, 'whose clock is that?'

'That's Mohammad Bin Qasim's. The hands have never moved, indicating that he never told a lie.'

'Incredible,' said the man'. And whose clock is that one?'

Angel responded, 'That's Liaquat Ali Khan's. The hands
have moved twice, telling us that he told only two lies in his entire
life.'

'Where's President Zardari's clock?' asked the man.

'Zardari's clock is in our office.

We are using it as a ceiling fan.
