When Leslie, who plays shop owner Debbie, notices how perky her employee Desi’s boobs are, she asks if she can feel for herself— and it’s mid-jiggle that Megan (who plays Desi) throws her head back and erupts with laughter.

Wearing a hot pink bra and underwear, Megan is clearly comfortable wearing next-to-nothing for the cameras, adding “Yeah, I'm just young,” when Leslie asks if they’re real.
