Again, stolen off Twitter this morning. There once was a man from Lahore Whose limericks stopped at line four When asked why this was He said: "Just because."
And to complete the set (not my own work): There was a young maiden from China With a feeling for rhythm much fina She stopped at line three. There was a young man from Peru Whose limericks stopped at line two. There was a young man from Verdun.
There was a young fellow from Merstham Who had boils on his bum and he cursed 'em When he sat on a chair 'Twas too much to bear So he got a sharp knife and he burst 'em.
