Milo Murphy's Law (2016)

S2E28 Cast Party

When Zack injures his leg by getting caught in a harp during an interpretive dance, his friends decide to throw a "cast party" in his honor. At the gathering, they take turns recounting their own mishaps and injuries, reminiscing about the times they broke something — all while avoiding any mention of Milo, Martin, or the infamous Murphy's Law, at least to their knowledge.
