'Mad Men': The Most Jaw-Dropping Moments of Season 5
Megan Draper (Jessica Pare)
Zou Bisou Bisou
We didn't know what to expect from the new Mrs. Draper, but an extremely sexy French serenade at Don's surprise party caught us (and him!) completely off-guard. Combine that performance with Don's freak-out and the reveal that Megan knows (and is nonplussed) about Dick Whitman, and suddenly we didn't mind waiting a year and a half between "Mad Men" seasons.
