One of my favourites,

If you all will shut your trap,
I will tell you 'bout a chap,
That was broke and up against it too,
He was not the kind to shave,
He was not the type to bathe,
But he heard the same old story everywhere.
Chorus
Tramp, tramp, tramp, keep on a-tramping,
Nothing doing here for you;
If I catch you 'round again,
You will wear the ball and chain,
Keep on tramping, that's the best thing you can do.
He walked up and down the street,
Till the shoes fell off his feet.
In a house he spied a lady cooking stew,
And he said, "How do you do,
May I convey some legal paperwork for you?"
What the lady told him made him feel so blue.
'Cross the street a sign he read,
"Singing lessons" so it said,
And he said, "Here is my chance, I'll surely try,"
And he tried to sing as he had done before,
Till his throat got rather sore,
But at bar-time he heard the Inn keeper cry–
Some time ago your guitar and vocals went bye bye.
