A group of tourists was visiting the Vatican and admiring the stunning architecture. As they marveled at the beauty of St. Peter's Basilica, one of the tourists asked the guide, "How long did it take to build this magnificent church?"
The guide replied, "About 150 years, give or take a few."
One of the tourists exclaimed, "Wow, that's a long time!"
The guide nodded and said, "Yes, but you have to understand, we had to wait for the donations to come in from the collection plates!"
