You never know when the link provided by Bee-dubya-ell might disappear, so I'm going to post the ones identified as Mason Williams pieces (are they???). There's from http://www.julesarts.com/literature/them/main.html. the Webmaster also posted some of his own compositions that are along the same vein, but I think I'll skip those.

Them Moose Goosers
by: Mason Williams

How about Them Moose Goosers,
Ain't they recluse?
Up in them boondocks
Goosin' them moose.

Goosin' them huge moose,
Goosin' them tiny,
Goosin' them meadow-moose,
In they hiny.

Look at Them Moose Goosers,
Ain't they dumb?
Some use an umbrella,
Some use a thumb.

Them obtuse Moose Goosers,
Sneakin' through the woods,
Pokin' them snoozy moose
In they goods.

How to be a Moose Gooser?
I'll turn ye puce.
Gitchy gooser loose and
Rouse a drowsy moose!
