Joke stolen from: Dosti Yaari

The little old lady got on bus and seated herself right behind the bus driver. Every ten minutes or so the lady would stare at the bus driver and ask with loud anxiety, "Have we reached Niagara Falls yet, Son?" "No, lady, not yet. I will let you know," he replied politely , every time she asked but with rising excitation. A few minutes later, she asked again "Are we there yet, son? Have we reached Niagara Falls?" * Once again, he replied "No, not yet. I'll let you know when we get there!" The hours passed, the old woman kept asking for Niagara Falls, and finally the town came into view. Sighing with relief, the driver slammed on the breaks, pulled over and called out, "This is where you get out, lady." "Is this Niagara Falls?" "YES!" he bellowed. "Get out!" "Oh, I'm going all the way to New York, son," she explained sweetly. "It's just that my daughter told me that when we come this far, I should immediately take my Heart medicines or I may die you know."
