When Kate McKinnon isn't hilariously impersonating Ellen, Justin Bieber, and her spot on impression of Hillary Clinton on SNL, she still finds ways to improvise in her film projects. She did just that on the set of Ghostbusters, thankfully most of them were caught on camera.
Youtube user Rayecheng uploaded a set of outtakes from the film, which features McKinnon throwing out dozens of one-liners and ad-libs, like when she greets Wiig with "you smell like coconuts", or "Hi, I'm Christina Aguilera". When she's describing Kevin, she describes him as "he's like a Christmas napkin, you know, you love looking at it but then you wipe it across your face once and then you throw it in the garbage and never think about it again."
That's not mentioning the ridiculous pun montage when describing their new hearst. She plays with a number of accents and mannerisms, which should have made keeping a straight face on set incredibly difficult.
