Speaking about rabbits... My sister used to have one as a pet. One day, I hid that rabbit somewhere safe and cooked steak for the family. They finished and said it was good. Then they asked what meat I used.
I said "rabbit" with a smile, when it was actually something else. Then my sister cried hysterically. She then proceeded to look for her rabbit everywhere she could think of, and still couldn't find it. She went limp. When she did, I took the rabbit out and gave it back to her.
It's a good prank, don't you think?
