In fact, until just now, I didn't think that there were any funny poems about chess on the internet at all. So, I shall take the liberty of reproducing this first I just found in full. Although of course after reading it, you might well still think that there are no funny poems about chess on the internet, which is how things go with matters of taste.
So without further ado, here is said Laureate-level effort:
I kill two pawns in the morning.
I kill two pawns at night.
I kill two pawns in the afternoon
And then I feel all right.
I kill two pawns in time of peace and two in time of war.
I kill two pawns before I kill two pawns.
And then I pwn them all.
And, yes, that's it. Although, I suspect the title and last line might need a note of explanation. The title stems from an internet in-joke about the bad English in a Japanese video game. While the word 'pwn' in the last line is internet slang for the word 'own'. 'Own', that is, in the sort-of online Americanese meaning of 'defeat' or 'dominate'.
So, did you like it or not? And can you do any better?
