Well, the platypus is an egg-laying mammal which would be an exception to the rule for mammals which typically give live-birth.
The platypus and 4 types of echidna (spiny anteater) are egg-laying mammals.
Whales, dolphins and porpoises are also mammals, though they don't have 4 limbs or fur/hair. They do breathe air, give birth to live young, nurse their young and are warm-blooded. And armadillos have no teeth.
