Here in Italy we are minutes ago from changing our currency to Euro. So I thought it would be interesting to find a mnemonic to remember how many old Italian Lira is worth an Euro.
This is what I came up with: my first little obfu. 
#!/usr/bin/perl
sub E{$%%2?$---:$;;++$%.($--$%)};$-=1E1,$_=(join'',E,reverse(E,E))/1E2
+,print;

    This is how many Guilders a Euro is worth: 
    $_="@{[(0..3)[(!$!+!$|)x2=>$;,2*!$?+1],7=>!!!$!]}";tr;tr:::, die;s/./$
+$./;;s;(?<=..)\.;;g;print

    Heh. I've done that, too, for the 'Deutsche Mark' or 'Deutschmark'. :)
    It was as some sort of revenge to my IT-Teacher who showed us how to write a DM<>Euro-Converter in GW-Basic. What a sick language it is...

    Just in case somebody is interested in my small converter: 
    print"Betrag? ";die"=",.01*int($$=<>)*
195.6," DM\n=",.01*int$$/.01956," E\n"
