"It gets better and better with each episode."

The third episode of the final series of Derry Girls aired on Tuesday night and many fans were left feeling a little sad that it marked the half way point to the end. However, the episode was hilarious as usual as the gang hopped on a train for a trip to Barry's amusement park in Portrush. Naturally, things didn't exactly go as planned for their big day out. The series has not disappointed with its celebrity appearances so far and this week's episode featured a special surprise cameo from actress Amy Huberman, who starred as a sexually frustrated and oversharing train worker called Tara. The star posted to Instagram to say filming the show was the best craic ever. https://www.instagram.com/p/Cc1B7GqoGx9/?utm_source=ig_embed&ig_rid=cf432ff7-e54b-4792-be3b-0977a55f1c38 Alongside an image of herself with Siobhan MacSweeney who plays Sister Michael and Nicola Coughlan who plays Claire Quinn, she wrote.: "Well that was THE CRAIC!
