It is said that as Brahma sat in deep meditation, ear wax (karna-shrotodbhava) flowed from Vishnu’s ears. Two ferocious demons, Madhu and Kaitabha, were born out of that wax. They performed great penance for thousands of years. Pleased by their penance, Lakshmi, the Lord’s consort, appeared before them and granted them the boon that they would die only when they so desired. Proud of their newly acquired asset, the demons became outrageously arrogant. They attacked Brahma, still meditating on his lotus stem, and stole from him the four Vedas. Though furious, Brahma was helpless in the presence of such powerful adversaries... (From here)

Wait--flowed?
I'm going to speculate that Vishnu's earwax is of great power.
Wait. Couldn't Brahma just melt them?
