How Thor left Asgard

The mighty Thor, the guy with Hammer
Was challenged only by His grammar
He never lost a single fight
but spelling words, that was His fright

Every time He had to boast
announced He won, from coast to coast
everyone was quite annoyed
of Hammer guy on steroid

He should have shut his boasting flap
Now He was challenged to a rap
words were flying, but not too long
He left in shame, now He is gone

conclusion:
If you are challenged with thinking, it's better to talk less
