Ek Bhi Nahin

A friend of mine has two kids. Once when they happened to be out of house, a guest came to their house and they were received by the kids. The kids invited them to drawing room and made them comfortable on the sofas. Those were the days of KBC - a popular game show on TV where Amitabh Bachchan used to play a game with the people where he used to ask them questions and give them four options to chose. The kids were impressed and decided that it was time they played KBC. So they asked the guests:

Aap kitne gilas paani piyenge? Inmein se ek chuniye

1. 1 Glass
2. 2 Glass
3. 3 Glass
4. Ek bhi nahin

The guests said "2 Glass" (The husband and wife had come and both were thirsty). The kids (in Amitabhh style):

Bilkul Galat Jawaab. Sahi jawaab hai "Ek bhi nahin"
