There used to be a whole culture of this sort of thing.  My favourite
one is an anagram generator:

#include <stdio.h> 

long a
[4],b[
4],c[4]
,d[0400],e=1;
typedef struct f{long g
,h,i[4]    ,j;struct f*k;}f;f g,*
l[4096               ]; char h[256],*m,k=3;
                     long n     (o, p,q)long*o,*p,*q;{
                     long r               =4,s,i=0;for(;r--;s=i^
                     *o^*p,                         i=i&*p|(i|*p)&~*o++,*q
                     ++=s,p                         ++);return i;}t(i,p)long*p
                     ;{*c=d               [i],n(a,c,b),n(p,b,p);}u(j)f*j;{j->h
                     =(j->g     =j->i[0]|j->i[1]|j->i[2]|j->i[3])&4095;}v(
j,s)f*               j; {int i; for(j->k->k&&v(j->k, ' '),fseek(
stdin,     j->j, 0);i=getchar(),putchar(i-'\n'?i:s),i-
'\n';);}w(o,r,j,x,p)f*o,*j;long p;{f q;int 
s,i=o->h;q.k=o;r>i?j=l[r=i]:r<i&&

         ?j->k:0){for(;!j&&((r=(r&i)-1&i)-i&&(r&p)?2:(x=0));j=l[r]);!
      x||(j->g&~o->g)||n                              (o->i,j->i,q.i)||(
    u(&q), q.j=j                                              ->j,q.g?w(&q

To run it, you need a dictionary such as /usr/share/dict/web2.  For
example:

        gson free software foundation           < /usr/share/dict/web2
        gson obfuscated c contest               < /usr/share/dict/web2
        gson unix international                 < /usr/share/dict/web2
        gson george bush                        < /usr/share/dict/web2
        gson bill clinton                       < /usr/share/dict/web2
        gson ross perot                         < /usr/share/dict/web2
        gson paul e tsongas                     < /usr/share/dict/web2
