Its also essential to make reference to the season in which the haiku is concerned.
Winter is early
leaves stain the snow tannin brown
Not crunchy, soggy.
As for a limerick:
There was a pig farmer from York
Who plugged up his teapot with cork
Quoth he, "Now its not runny
Even if it tastes funny
But the cork is much better than pork."
Lame but the best I can do on short notice.
And you have to find me to maim me, bw7.
