My Step-Sister's Bachelorette Party!

The setup

Camilla is getting married, and she needs help zipping up before the night begins. Her stepbrother does the honors and learns the bachelorette plan involves a strip club, three flirtatious friends and a house rule that cameras capture the whole night. Episode 1 gets him pulled into the group with a straightened tie and a teasing question about whether he's jealous. In episode 2 the party moves from club to club, the friends dare the bride, and Camilla ends up on her stepbrother's lap in the back of a car. The night is far from over: the bride has more she wants to show him before it ends.

Why it earns its number

The party-night format gives this one an energy the other stepsibling cards lack: cabs, clubs, three friends who keep scoring points and a bride on a last-night mission. It's built around a single evening, so the pace is quick and the dares escalate.

Who should collect it: For anyone who wants a loud, funny, flirtatious night out with a bride, her friends and one reluctant plus-one.
