One of the challenges of a show like “Nightly Pop” is keeping things fresh show after show. This is challenging enough for a series that airs once a week, but the difficulty level shoots through the roof when you’re hosting four shows a week. Nina Parker and her co-hosts handle this by constantly keeping each other on their toes — which in turn, keeps viewers on their toes, waiting to see what they’ll do next.

Some of Parker’s favorite moments have come from episodes when they planned to spring surprises on each other, such as their prank shows, which she considers both her favorite and least favorite episodes. “I hate them, but on camera, it does end up being really funny and our fans really enjoy it,” she said. “We do a lot of pranking on each other.” Holidays also bring opportunities for memorable moments. “Our Halloween shows are always really fun when we get dressed up and surprise each other with our costumes, because we don’t tell each other what we’re going to be,” she said. “Whenever one of us has a birthday, there’s always some cool surprises.”
