Namaste,

I came across this amazing verse of Sri Sundara Murthi Nayamar.It is the first prayer uttered by the Saint Devotee on Lord Shiva.The story behind addressing the Lord as a Crazy one is given at the end.

Sri Sundarar:

O Crazy One! O the One who is wearing the crescent moon!
O the great One! O the One who bestows blessings!
You have installed yourself in my mind.
I remember you always without forgetting in any manner.
O father in the aruL thuRai temple in the town of veNNey ~nallUr on the southern banks of the peNNai river!
How can I say any more that I am not your slave?

(Verse in Tamil)
piththA piRai sUdI perumAnE aruLALA
eththAn maRavAdhE ~ninaikkindREn manaththu unnai
vaiththAy peNNaith thenbAl veNNey ~nallUr aruL thuRaiyuL
aththA unakku ALAy ini allEn enal AmE.

From the internet:
ArUran was the son of a temple priest. When he was a young child, the local king liked ArUran so much that he raised him in his palace as if he were his child. When ArUran was about 16 years or so, his parents arranged his wedding. On the day of the wedding, an old brahmin came into the wedding hall and stopped the marriage saying that ArUran was his slave. ArUran called the old man a crazy person and questioned how a brahmin could be a slave to another brahmin. The case went to the village elders. The village elders investigated the evidence presented by the old man and decided the case in favor of the old man. Thus, ArUran was declared the slave of the old man. The old man led
ArUran (and others) into the temple and disappeared only to appear as Siva and pArvathi to ArUran. Siva reminded ArUran of his past and asked him to sing. ArUran did not know how to start. Siva instructed to him to start the song with the first words that ArUran used when he saw the old man in the wedding hall. This is that very first song sung by ArUran. That is why this song starts by addressing the god as the “crazy one”.
(su~ndharar is the name ArUran in his previous life. After the above event, he came to be referred by that name only).

Legend states that while Sundarar was being married, the service was interrupted by an old ascetic who asked for Sundarar as his servant, making a name sake claim that Sundarar's "grandfather pledged him" according to an ancient palm leaf manuscript in his possession. Sundarar and those assembled at the wedding were outraged and called the old man a madman (piththaan: Tamil). But a court of Vedic scholars concluded that the palm leaf was legally valid. Crestfallen, Sundarar resigned himself to servitude in the old man's household and, following him to Thiruvennainallur village, was led to the Thiruvarutturai Shiva temple.
The old man was said to be Shiva (Lord Thiagaraja) himself, who told him: " That the document shown was only a name sake reason and he wanted sundarar to be reminded of his actual form as Alalasundarar a servitor in lord's kailasam, who had to be born in earth both due to moments of worldly thoughts that overcame him as well as due to the fact that the southern tamil region that had done great thavam during kali age need be blessed with an account on lives of great nayanmars called tiru thondar thokai.You will henceforth be known as Vanthondan, the argumentative devotee. Did you not call me a mad man just a short while ago? Begin your hymn addressing me 'O mad man!'". Lord sivan had also advised vanthondar to" while on earth sing of us in words of Tamil"
