Anatomy of a hilarious anecdote

Someone I work with thinks they're hilarious. This is a story they told this morning...

SET-UP: Another co-worker mentioned that a shirt they washed last night is ruined because it shrunk in the washing machine.
EXPRESSION OF EMPATHY: "That happens to me too!"
ESTABLISHMENT OF PREMISE; IN THIS CASE, A ROUTINE THAT SHOULD YIELD CONSISTENT RESULTS: "I wash my clothes the exact same way every time."
WILDLY UNUSUAL VARIANCE: "And sometimes, something will shrink."
INCREDULOUS REACTION, DELIVERED VIA CURRENTLY RELEVANT, ALBEIT HIGHLY OVER-USED POP CULTURE CATCH-PHRASE: "I'm like, 'really?'."
HILARITY ENSUES: "Ha ha ha ha ha ha!"
