"Once, Kevatta, this train of thought arose in the awareness of a certain monk in this very community of monks: 'Where do these four great elements — the earth property, the liquid property, the fire property, and the wind property — cease without remainder?' Then he attained to such a state of concentration that the way leading to the gods appeared in his centered mind. So he approached the gods of the retinue of the Four Great Kings and, on arrival, asked them, 'Friends, where do these four great elements — the earth property, the liquid property, the fire property, and the wind property — cease without remainder?'
"When this was said, the gods of the retinue of the Four Great Kings said to the monk, 'We also don't know where the four great elements... cease without remainder. But there are the Four Great Kings who are higher and more sublime than we. They should know where the four great elements... cease without remainder.'

"So the monk approached Sakka, the ruler of the gods, and, on arrival, asked him, 'Friend, where do these four great elements... cease without remainder?'
"When this was said, Sakka, the ruler of the gods, said to the monk, 'I also don't know where the four great elements... cease without remainder. But there are the Yama gods who are higher and more sublime than I. They should know...'...
"The Yama gods said, 'We also don't know... But there is the god named Suyama... He should know...'...
"Suyama said, 'I also don't know... But there is the god named Santusita... He should know...'...
"Santusita said, 'I also don't know... But there are the Nimmanarati gods... They should know...'...
"The Nimmanarati gods said, 'We also don't know... But there is the god named Sunimmita... He should know...'...

"When this was said, the gods of the retinue of Brahma said to the monk, 'We also don't know where the four great elements... cease without remainder. But there is Brahma, the Great Brahma, the Conqueror, the Unconquered, the All-Seeing, All-Powerful, the Sovereign Lord, the Maker, Creator, Chief, Appointer and Ruler, Father of All That Have Been and Shall Be. He is higher and more sublime than we. He should know where the four great elements... cease without remainder.'
"'But where, friends, is the Great Brahma now?'
...
"Then it was not long before Brahma appeared.
"So the monk approached the Great Brahma and, on arrival, said, 'Friend, where do these four great elements — the earth property, the liquid property, the fire property, and the wind property — cease without remainder?'
"When this was said, the Great Brahma said to the monk, 'I, monk, am Brahma, the Great Brahma, the Conqueror, the Unconquered, the All-Seeing, All-Powerful, the Sovereign Lord, the Maker, Creator, Chief, Appointer and Ruler, Father of All That Have Been and Shall Be.'
A second time, the monk said to the Great Brahma, 'Friend, I didn't ask you if you were Brahma, the Great Brahma, the Conqueror, the Unconquered, the All-Seeing, All-Powerful, the Sovereign Lord, the Maker, Creator, Chief, Appointer and Ruler, Father of All That Have Been and Shall Be. I asked you where these four great elements — the earth property, the liquid property, the fire property, and the wind property — cease without remainder.'

"Then the Great Brahma, taking the monk by the arm and leading him off to one side, said to him, 'These gods of the retinue of Brahma believe, "There is nothing that the Great Brahma does not know. There is nothing that the Great Brahma does not see. There is nothing of which the Great Brahma is unaware. There is nothing that the Great Brahma has not realized." That is why I did not say in their presence that I, too, don't know where the four great elements... cease without remainder. So you have acted wrongly, acted incorrectly, in bypassing the Blessed One in search of an answer to this question elsewhere. Go right back to the Blessed One and, on arrival, ask him this question. However he answers it, you should take it to heart.'
I cracked myself and laughed so hard when I found this part of the sutta.
) in his teaching but, like Perkele, I can't remember specific instances except that there are several in his debates with Brahmins.
