This is one I like and hope you'll enjoy:
The following poem appeared in INFOCUS magazine. The original
authors were Fred Bremmer and Steve Kroese of Calvin College & Seminary
of Grand Rapids, MI.
A poll conducted among INFOCUS readers had established "waka" as the
proper pronunciation for the angle-bracket characters <, though
some readers held out resolutely for "norkies."
The text of the poem follows:
<>!*''#
^"`$$-
!*=@$_
%*<>~#4
&[]../
|{,,SYSTEM HALTED
The poem can only be appreciated by reading it aloud, to wit:
Waka waka bang splat tick tick hash,
Caret quote back-tick dollar dollar dash,
Bang splat equal at dollar under-score,
Percent splat waka waka tilde number four,
Ampersand bracket bracket dot dot slash,
Vertical-bar curly-bracket comma comma CRASH.
