Kate wanted to show what she used to do for fun in high school and volunteered Cash for a belly button piercing.
Kate attempted to give Cash a belly button piercing, which he was reluctant to undergo.
They played rock, paper, scissors to determine who would get pierced, with Cash losing and being chosen.
The loser had to drink pond water or get a piercing, leading to Cash's reluctance and eventual ear piercing.
Cash agreed to get his ear pierced instead of his belly button after much reluctance and negotiation.
The group was initially shocked but later acknowledged Kate's experience with piercings.
The episode concluded with Kate successfully piercing her own ear and the group discussing the experience.
