Who Eats Stinky Fruit Anyways?

I really don't see how people can eat stinky fruits like durian or jack fruit because they stink so badly!  Plus why do they have to have a spikey outer shell?  It's not like they smell delicious so animals would seek out to eat them so they had to evolve with a protective outer layer to protect themselves.  So what gives?  The spikes is a turn off and the smell is another turn off.  How can you eat that?

Giant stinky fruit!
