Gwyneth Paltrow returned to Glee as sultry substitute teacher Holly Holiday on Wednesday – and it was hard not to laugh at her candid approach to sex education.
Case in point: When uptight Emma asks Holly why celibacy isn’t a valid option for teens, Holly replies, “I just don’t think it’s that realistic. It’s like saying vegetarianism is an option for lions.”
After leading a “health and wellness jazzercise class,” Holly promises a smitten Mr. Schuester that she’ll “slip in a little lesson about how to avoid STDs” while the glee clubbers think they’re prepping for regionals.
