Crazy Calf Characteristics

On Saturday morning I walked out to the barn to find a new little heifer calf out of one of our best cows.  I stood there watching for a while noticing she seemed to be trying to push out manure, but it just wasn't coming.  I went over to take a closer look to find that our new addition was born with out an Anus.  She now has a temporary one thanks to my Dad's pocket knife, but I'm not real sure how this whole situation will turn out. 

Just wondering if anyone else has ever had this happen or had any other crazy characteristics? Might be fun to see who has the best ones.

A friend had a handful of calves born last year like that.  First couple he didn't realize what was happening until they died and he realized they had no opening.  Never thought to ask him if the others survived.  First time I had heard of it. 
The only reason he told me about this is that we had a weak calf born last year and we were trying to get it up and moving and when I mentioned it to him, he said, "Does it have a butt hole?"  Of course I thougt he was joking until he explained his situation to us.  Very strange to have not only one, but several born the same year.  By the way, our calf had all the right openings!! 

A few crazies I've seen, or had friends see:
-A calf that had a tail growing out of where his testicles would have been, and he had no back bone. (was dead by the time we pulled him)
-A calf born with no eyes.  But he didn't even have eye sockets, the bone was solid where his eyes should have been and the skin went right over top
-A calf born with 2 head
-A calf born with 5 legs
-the craziest one, a friend of mine had, it was a cow that wasn't having her calf, so he reached inside, and it was all soft and mushy, so he assumed that the calf was rotting inside, until the calf started sucking on his finger.  he pulled the calf, only to realize this calf had no hide! so it was just raw muscle, you could see his heart, his blood pumping through his body and everything! Needless to say, he died shortly after, but because it was such a crazy phenomenon, he took the calf into the vet, and it was something like a 1 in 5 million chance or something crazy!

Not sure if this is correct term but dairy industry and a few angus pedigrees over the years have had genetic defect I believe was called Atresia ani or something of the sort.  Believe it is a recessive genetic defect trait.  Calves have no anus and generally missing last few inches of intestine.

Worked on a ranch that had Horned Herefords.  Had a few two headed calves, and one calf born inside out, that was interesting.

Father-in-law's Angus have had a few with no tails and extra legs.

I have seen atresia ani before but I don't know that it has been proven to be a genetic thing, easily could just be congenital.  You can perform a surgery and great an anus for them, it has been done successfully.  Coolest one I saw was actually a colon atresia.
