Three brothers were competing to see who was able to give their elderly mother the best birthday gift

The first one bought her a mansion.
The second one bought her a Porsche.
The third one, knowing how religious their mom is, bought her a remarkable parrot. It took 18 monks 10 years to teach him how to recite the whole Bible. It’s one of a kind, it cost 20 million dollars.
After some time, their mother sent out her letters of thanks:
"John," she wrote to the first one, "The mansion you bought is too big. I live in only one room, but I have to clean the entire house."
"Peter," she wrote to the second one, "I’m too old to travel. I stay most of the time at home, so I rarely use the Porsche."
"Dearest Samuel," she wrote to her third son, "You have the good sense to know what your mother likes. That chicken was absolutely delicious!"
