Gwyneth Paltrow returned with a bang -- so to speak -- to Glee Tuesday night, reprising her role as quirky substitute teacher Holly Holliday.

The episode focused on SEX-SEX-SEX, with Holliday attempting to teach the kids -- and even some adults -- about the birds and the bees. (And yes, at one point, she even whips out a condom and a cucumber, scaring the kids off of salads for life).

Paltrow sang several songs -- kicking off with a rousing cover of Joan Jett's Do Ya Wanna Touch Me, later followed by Fleetwood Mac's Landslide, and a fabulous duet by Gwyn and Matthew Morrison of Prince's Kiss.
