Was it as good as the blind joke on the Vicar of Dibley?
Alan Davies (the QI Alan Davies) made an interesting observation this morning. He felt that the joke wasn't meant as a reference to alopecia per se, but that Chris Rock made the quick reference to GI Jane solely based on seeing a woman with a shaved head and wearing a green outfit. Not sure I buy it myself, or if Chris Rock has mentioned that that's what he did mind?
