What are your bunny methods?

I just got two 6 week old rabbits (brothers) named Oreo (who is black and white) and Blueberry (who is blue) from our friends farm. They are just the cutest little things! We keep them in the [bunny-proof] bathroom along with their litter box, water, pellets, hay, occasional fruit/veg, toys, etc. I've owned bunnies before, and I if I have a question i'll usually research it. But right now I want your personal opinion. What do you do when your bunnies are naughty? Like when they nip, scratch, dig, etc. Also, what tricks have you taught your rabbits? Please, pour out your rabbit training tecniqes, tips, and etc. Thanks!
