Ellen also hid in Paulson's dressing room and jumped out at her, scaring her before the show's taping, then she had a crew member sneak up and scare her from behind while they were on stage.
But the best part was while she was recovering from her second scare, a clown - one of Paulson's biggest fears - jumped out of the ottoman next to her seat, at which point Paulson collapsed on the ground, hugging Ellen's legs before she gave up and just crawled under the coffee table.
Morals of the story: People getting frights will always be hilarious, and never, ever trust Ellen DeGeneres.
