A small banana is a roughly 5 inches tall and 100 gms in weight. Around the same as a cell phone. Let the significance of the size not be lost on you.

A man going home from work likes to buy something to eat before the commute.

Men are normally paranoid about their belongings, specially in public areas and keep checking their pockets to ensure that the wallet, cell phone etc are there.

Normally the cell is kept in the top right hand pocket of the shirt.

Most people in trains are helpful and point out if you forget something or the other while getting off.

Bananas are seen as nice nutritional food by the common man.

A man can eat one banana easily, the second one may be eaten after some time.

Bananas normally get squashed quite easily.

Your shirt pocket can’t hold too many things together.

People normally keep the same stuff in the same pocket everyday. Habit.

Bananas are often sold as a pair. 5 for 2

People normally read books in trains to pass time.

Now to connect the threads...

One man bought two bananas for five bucks. He ate one. He then boarded the train. He put the second banana in his shirt pocket. When he sat he put the cell phone beside him. He began reading a book. When his station came he did a mental check. His felt his wallet and his cell and got up and began to leave. The guy sitting opposite pointed out that he left his cell behind. The man turned in horror to find his cell on his seat. He then realized that the weight he felt in his top pocket was actually the banana and not the cell as he made it out to be.

I am that man.
