Stupid

The other day I saw a duck,
It was in a pond and it was stuck,
Ice had frozen the surface solid,
Its legs were trapped, and so I hurried,
Over to see how I could help,
And it was at that moment that I smelt,
Something funny and turned around,
I saw him and without a sound,
He plunged his sword into the ice,
And I fell through, so heres my advice:

If it is summer and the weather is hot,
There shouldnt be any frozen ponds,
If you go on that ice intentionally,
Then you are 100% as stupid as me.
