Grammar

Remember, the world-famous speech delivered by Chatur on Teachers' Day? No one can ever forget the misplaced words and his hilarious tone of Chatur, but what most of us couldn’t notice was the banner hanging right behind Chatur. The banner read 'Teachers Day ' which is grammatically wrong. It is ‘Teachers' Day’ and not ‘Teacher’s Day’. Such was the power of Chatur’s speech that we just ignored the grammatical error completely.
