Johnny L.A.:
The “rickety tickety tin” song is one verse from a song by Tom Lehrer. The other verses are equally ghoulish.
Thanx! 
Irish Ballad (by Tom Lehrer)
About a maid I’ll sing a song,
Sing rikitty-tikkity-tin;
About a maid I’ll sing a song,
She didn’t have her family long;
Not only did she do them wrong,
She did every one of them in, them in,
She did every one of them in.
One mornin in a fit of pique
Sing rikitty-tikkity-tin;
One mornin in a fit of pique
She drowned her father in the creek,
The water tasted bad for a week
And we had to make do with gin, with gin;
We had to make do with gin.
She set her sister’s hair on fire,
Sing rikkity-tikkity-tin;
She set her sister’s hair on fire,
And as the smoke and flame rose higher
She danced around the funeral pyre
Playing a violin, olin,
Playing a violin.
She weighted her brother down with stones,
Sing rikkity-tikkity-tin;
She weighted her brother down with stones,
And sent him off to Davy Jones.
All they ever found were bones,
And occasional pieces of skin, of skin,
And occasional pieces of skin.
One day when she had nothing to do,
Sing rikkity-tikkity-tin;
One day when she had nothing to do,
She cut her baby brother in two
And served him up as an Irish stew,
And invited the neighbors in, bors in,
And invited the neighbors in.
When at last the police came by,
Sing rikkity-tikkity-tin;
When at last the police came by,
Her little pranks she did not deny,
To do so she would have had to lie,
And lying she knew was a sin, a sin,
Lying she knew was a sin.
My tragic tale I won’t prolong,
Sing rikkity-tikkity-tin;
My tragic tale I won’t prolong,
And if you do not enjoy my song,
You’ve yourself to blame if its too long,
You should never have let me begin, begin,
You should never have let me begin.
[Hijack] Oooh EvilBeth, you are so hired! We can only agree that Blarney was one of the greatest threats to civilization since The Smurfs.
[smurf voice] “No, you are not capable of self determination. You must obtain consensual opinion / reality for all that you do!” [/smurf voice].
The vacuous / vacuum / vertiginous void that encompasses Blarney is so mindnumbing as to make soap operas look like Fine Art.

Yankee Doodle went to town
a riding on his mother
every time he hit a bump
he had a baby brother…
You know, it took me years to get that one.
I was going to post about Greasy Grimy Gopher Guts, but I see Ukulele Ike already has. Look through it carefully and you can find the one song I contributed.
