believe it or not, my kids had a bunny when they were small. it bit them all the time so we had to get rid of it. there was a guy who bred rabbits so we gave it to him. he was trying for exactly that: one ear up, one ear down. unfortunately, it bit and killed it's male mate and he had to put the rabbit down. it was too dangerous to keep.
i think bugs bunny has ears like that and that's why he tried for it.
the rabbit's name was Esther Bunny. guess when we got it. :lol: :lol:
