I use a huge wooden spoon inserted into the body cavity, and then lots of paper towels wadded up to facilitate flipping the bird.
Or rather, I used to... last year I had the bird spatchcocked (or butterflied, but the other word is so much more fun to say!) and just roasted it flat. It was done in a fraction of the normal time! Not so great for that Norman Rockwell type of presentation, but we're not so fussy around here.
