Banta, Mr Mukherjee, an old lady and a beautiful blonde find themselves together on a train.
The train passes through a tunnel and in the darkness a loud slap is heard. When out of the tunnel and in the light, they see that the Banta has a red five finger mark on his cheek.
The blonde is thinking: Banta must have tried to grope me in the dark and mistakedly groped the old lady, so she slapped him.
The old lady is thinking: that guy must have groped the blonde in the dark and she slapped him.
Banta is thinking: Mr Mukerjee must have groped the blonde in the dark and she mistakedly slapped me instead of him.
Mr Mukherjee is thinking: I can't wait for the next tunnel so I can slap that damn Banta again!!!
