"America's Got Talent" winner Terry Fator just reached a milestone at his Vegas show -- and marked it by debuting a new dummy!

Fator, who won the first season of the NBC talent competition, celebrated the one-year anniversary of his Mirage show over the weekend -- and showed off Wrex, the latest wisecracking, crash test-inspired puppet he lends his voice to.
Don't worry -- the doll may be wooden, but the show is anything but.
