Because it was lunchtime and I wanted to make sure I was still employable...

static MyLinkedList<T> ReverseLinkedList<T>(MyLinkedList<T> linkedList) { if (linkedList.Next == null) return linkedList;

  var newTail = linkedList.Next;
  var reversedList = ReverseLinkedList(linkedList.Next);
  newTail.Next = linkedList;
  linkedList.Next = null;

  return reversedList;
}
