While promoting How to Be Single on Late Night with Seth Meyers, Alison Brie shared a memory from the set of Mad Men that everyone can relate to, give or take the vintage costume. In brief, Brie came just short of understanding how she was supposed to wear her costume such that she pissed all over it. Brie says it more eloquently.

"This is getting sort of graphic," she said, before describing the "crazy hover" she executed while peeing. Alas, the public bathroom squat which all ladies are familiar with did not ensure Brie's accuracy. She did "a full pee" onto her underwear and into her costume. Then she went straight to set.
