He weighs in at 22 pounds and measures a little over 3 feet. he is a breed of rabbit called german giant (how appropriate!). This is his owner, Hans Wagner, struggling to hold him up. from the NY Post article:

We don't feed him an unusual diet said Wagner. He goes through more than his brothers and sisters, but he eats the same food mix. His favorite food is actually lettuce. He can never get enough of it.

LOOK AT THOSE FEET!
