Lateral Thinking

(Thanks to Nachiket for this amusing real
life story. The boy in this story is
actually one of the family friend of
Nachiket's family.)

There was a boy at IIT, Kharagpur. There
were a lot of mosquitoes at IITKh so he had to
set up mosquito net before he could sleep.
Once unfortunately, this mosquito net
got a hole. Mosquitoes used to enter the
net through that hole and trouble the boy.

He simply made another hole in the
net and connected a flexible tube from
one hole to the another.

Poor mosquitoes, they did not know who
they were pitted against !!! :D
