(This is a very old story that I had heard and thanks to sri Rajagopal srinivasan, I remembered it)
Lakshmana fell in the battle with Indrajit,
And Hanuman was given order to bring Sanjeevini herb,
And he flew in the sky , could locate the mountain,
But not the herb, brought the mountain and Lakshmana got up.
After reaching Ayodhya , Hanuman submitted a bill,
For drawing his tour allowance and it was rejected,
The accounts officer told , Rama was not the king ,
And so could not sanction the tour, Hanuman being,
A class four officer is not entitled to fly and as it was ,
Not needed to bring the mountain , excess baggage is not allowed.
Hanuman made representation to Lord Rama who was,
Unable to instruct his accounts officer and requested him,
To withdraw his bill but the finance minister of Rama,
Called the accounts officer and threatened him with dire consequences.
Next day the bill was passed and now the accounts officer wrote,
Though Rama was not the king , as he was officer in charge at Ayodhya ,
And he could sanction the tour and allow Hanuman to fly due to emergency,
And allow him excess baggage because had Hanuman brought ,
The wrong medicine , he has to again undertake the tour and that too by air.
