Some limericks 4 U

Limericks are "five-line poems with strict form and are frequently witty or humorous, and sometimes obscene with humorous intent" (taken from http://en.wikipedia.org/wiki/Limericks). Below is a limerick on limericks:

The lim'rick packs laughs anatomical
Into space that is quite economical;
But the good ones I've seen
So seldom are clean,
And the clean ones so seldom are comical.

Here are some more examples:

1) There once was an old man of Lyme
Who married three wives at a time;
When asked, "Why a third?"
He replied, "One's absurd,
And bigamy, sir, is a crime."

2) There was a young fella named Weir
Who hadn't an atom of fear;
He indulged a desire
To touch a live wire-
Most any last line would do here.

3) God's plan made a hopeful beginning
But Man spoiled his chances by sinning;
We trust that the story
Will end in God's glory,
But at present the other side's winning.

4) There was a young girl of Natchez
Whose garments were always in patchez;
When comment arose
On the state of her clothes
She drawled, "Where Ah itchez, Ah scratchez."

5) A daring young lady of Guam
Observed, "The Pacific's so calm
I'll swim out for a lark."
She met a large shark...
Let us now sing the 90th Psalm.

6) A senora who strolled on the Corso
Displayed quite a lot of her torso;
A crowd soon collected
And no one objected
Though some were in favour of more so.

I pity the poor linguistically-challenged visitor who find themselves unable to appreciate the above limericks...
