Mr & Mrs
You need
Ten questions, and the groom's answers recorded in advance.
Ask the groom ten questions about the relationship a week early — where they met, who says sorry first, what she orders at a bar — and film him answering. On the day, ask the bride the same questions. Every mismatch is a sip.
Why it works: it is the only game where the groom is in the room without being in the room, and it makes everyone feel involved in the couple rather than just the party.
