This program is a re-written CGI version of Travesty, which is featured in Programming Perl and was first published in Byte in 1984 or 1985 (a Pascal version). The Programming Perl version never seemed to work right... this version rules and produces hysterically garbled output in the style of the input, regardless of what language it's written in.
