Lord Ganesh is very fond of sweet pudding or balls of rice flour with a sweet core. On one of His birthdays, He was going around house to house accepting the offerings of sweet puddings. Having eaten a good number of these, He set out moving on His mouse at night. Suddenly the mouse stumbled--it had seen a snake and became frightened--with the result that Ganesha fell down. His stomach burst open and all the sweet puddings came out. But Ganesha stuffed them back into His stomach and, catching hold of the snake, tied it around His belly.Seeing all this, the moon in the sky had a hearty laugh. This unseemly behaviour of the moon annoyed Him immensely and so he pulled out one of His tusks and hurled it against the moon, and cursed that no one should look at the moon on the Ganesh Chaturthi day. If anyone does, he will surely earn a bad name, censure or ill-repute.
