Oohh... this would be so good for the underhanded C contest! Just mix is up with the comments which make the `do` look like (assuming good actor) an accidentally wrapped comment.

    /* The following code does something, so here's the

    */ do
    printf("hey\n");
    
    /* And now just count down */
    while (some_check(--i));

Now spot that in a large file of real code!
