Actually it’s the Higgs field, theorized to exist at every point throughout the universe, which gives particles mass in proportion to their interaction with that field. The Higgs boson is simply the smallest quantum of excitation of that field.
Finding the boson proves the existence of the field though, so as Arlo so aptly put it, it’s a Big Deal.
Janis is just pulling his leg, though. Pretty funny, Mrs. Day!
