Kibaki, Raila, Ngilu and Martha Karua travelling in a train

Raila, Kibaki, Ngilu & Martha Karua are traveling in a train. The train
suddenly goes through a tunnel & it gets completely dark. Suddenly there
is a kissing sound & then a slap! The train comes out of the tunnel.
Ngilu & Raila are sitting there looking perplexed. Kibaki is bent over holding
his face, which is red from an apparent slap. All of them remain
diplomatic & nobody says anything.
Ngilu is thinking:
‘These men are all crazy after Martha Karua’. Kibaki must have tried to
kiss her in the tunnel. Very proper that she slapped him.’
Martha Karua is thinking:
‘Kibaki must have moved to kiss me & kissed Ngilu instead & got slapped.’
Kibaki is thinking:
‘Damn it, Raila must have tried to kiss Martha Karua, she thought it was
me & slapped me.’
Raila is thinking:
‘If this train goes through another tunnel, I could make another kissing
sound & slap Kibaki again’
