Yes, there are many vegetables that aren't healthy for rabbits. Fresh vegetables should be divided into four categories:
See the related question below for more info and helpful links about a healthy rabbit diet.
Veggies that should be avoided entirely include corn, because rabbits can't digest it and it can lead to gut impaction; also the tomato plant, which is toxic (although the tomato fruit itself is okay as a treat). See the related link below about dangerous plants for a much longer list.
Veggies that are good as a treat include most fruits and vegetables, like carrot, squash, berries, apple.
Dark leafy greens that are good in moderation include cruciferous vegetables (cabbages and veggies related to cabbage). These foods can give rabbits gas, which can lead to serious illness. Some rabbits are fine with these veggies in moderation, while other rabbits get gas very easily - they shouldn't eat these veggies at all. The key is to know your rabbit and watch for signs of illness. For more information, see the related question below about signs of illness in rabbits and going to the vet, and see the link about cruciferous veggies.
Dark leafy greens that are good on a regular basisinclude dandelion, carrot tops, basil, and Romaine lettuce.
Rabbits will eat cheez-its and they will love them, but the salt is really bad for them -- not to mention the "cheez" flavoring. A healthy treat for bunnies is Post Grape Nuts. It's whole grain with no additives and bunnies love it.
No, rabbits should not eat uncooked rice regularly. While a small amount will not harm your rabbit, the majority of their diet should be hay, pellets, and fresh vegetables.
A 3 month old rabbit should eat a lot. Fresh rabbit mix in a bowl everyday. Also Fresh Carrots, spinach, corn on the cob, silverbeet, apple, pear. Throw away left overs every day. Paula
Pellets give the rabbit fiber and nutrients. You need to give your baby rabbits pellets. It is needed in adults but not needed as much. Vegetables are also important but try not to give your rabbit too much veggies. Make sure to give them plenty of hay.
Too many fruits can make a rabbit sick. Fruits are optional treat foods in a rabbit's diet. The House Rabbit Society recommends no more than 2 tablespoons of fruit a day (or other treats) for a normal, healthy 6 pound rabbit.
If your rabbit hates vegetables, try leafy greens. If she won't eat leafy greens, buy commercial rabbit pellets to feed her.
Wild rabbits eat any edible grass or plant material they can find during dawn and dusk (that is when they are most active). Domestic rabbits should eat rabbit pellets, hay, fruit, and vegetables.
Rabbits eat vegetables, rabbit pellets, and Monty Python's Knights of the Round Table.
This rabbit will eat the same thing any rabbit eats. Alfalfa pellets and most vegetables and lettuce. Fiberous fruits like apples and pears.
Algae and fresh vegetables

It gnaws mouthfuls off then chews them.
They eat their rabbit food and some vegetables.
Yes. But give the rabbit variety, not just parsley. Vets recommend 1 cup of vegetables for every 3 pounds of rabbit weight. Example, if your rabbit weighs 6 pounds, he should get 2 cups of vegetables every day. :)
