just because some folks don't know - it can be dangerous to put rabbits on their backs "Purposely inducing tonic immobility by laying a rabbit on his back can cause him serious stress. While he may appear relaxed during the trance-like state, afterward his heart and respiration rate is likely to be very high. A study led by Dr. Anne McBride of the University of Southampton found that rabbits show signs of extreme stress after an episode of tonic immobility. Another danger of placing a rabbit on his back is that he could break his back if he struggles against being turned over." http://animals.pawnation.com/laying-rabbit-...
