I'll give you one that my son wrote for an English class when he was in 5th grade.

You should get your son to post his limericks here, Owlbow. Before long [if not already] he will be showing the rest of us a rhyme or two.

Seriously, please tell him we loved his limerick, and we would welcome more. He has a talent for it.

With themilum as the chief judge of limericks around here, he can be certain he will always come out ahead of at least one limerick poster -- c'est moi. :)
