"Ray Parker Jr. is in this week's episode which is really cool because he sang, 'Who're you gonna call? Ghostbusters!'" Feldman spilled to ETonline. "There's a whole lot of Ghostbusters in this episode… [HenryZebrowski and I] got to wear the cool Ghostbusters outfits and then Cristin [Milioti] and Lenora [Crichlow] dressed up as Laverne and Shirley, so it was a whole lot of fun."

Feldman added that it was a "magical moment" for him to step into the Ghostbusters costume, and he loves that A to Z's creator Ben Queen consistently treats fans with '80s throwbacks throughout the season. "It's so much fun," Feldman gushed. "I'm roughly the same age as our creator [Ben] so it's just a lot of callbacks to our youth and it happens about one an episode now."

So far, each episode of A to Z has been eerily relatable for those in today's dating world, and Thursday's episode is definitely going to resonate with viewers with this touchy topic: What happens to the relationship with your best friend when you start dating someone new?

"There's an established history between [Andrew] and my friend and [Zelda] and her friend, and now this relationship has kind of disrupted all of those friendship transitions that everyone has and so of course conflict will ensue," Feldman answered. "I think this is the first time you see Stu and Stephie team up a little bit and agree on something even if it is being mad at us."

A to Z airs Thursday at 9:30 p.m. on NBC.
