"in a sentence"

Another great face-maker is California State Prison inmate #B33920. When an interviewer asks the inmate to tell him ("in a sentence") who he is, the inmate provides a mimed response, then this poem:

NOBODY

I'm nobody

I'm a tramp
A bum
A hobo

I'm a box car
And a jug of wine

And a straight-razor
If you get too close to me
