A mother-in-law visits her son-in-law before leaving for a
trip.
They are sipping coffee and chatting. Suddenly, mother-in-law looks
at the clock and jumps off her chair exclaiming, "My god!
It's already three P.M. I'm about to miss my train!"
She begins to gather her luggage together. At this moment, her
granddaughter runs up to her and before he can stop her, announces,
"Don't hurry, granny! Daddy moved the clock two hours ahead!"
