Funny that they never site the account in Luke: from online NWT:
Moreover, just as it occurred in the days of Noah, so it will be also in the days of the Son of man: 27 they were eating, they were drinking, men were marrying, women were being given in marriage, until that day when Noah entered into the ark, and the flood arrived and destroyed them all. 28 Likewise, just as it occurred in the days of Lot: they were eating, they were drinking, they were buying, they were selling, they were planting, they were building. 29 But on the day that Lot came out of Sod′om it rained fire and sulphur from heaven and destroyed them all. 30 The same way it will be on that day when the Son of man is to be revealed.
Sounds pretty local to me: parallel language
