Last night’s episode of Dancing With the Stars presented the stars with a unique challenge — the "Switch-Up Challenge," to be exact.

The stars and their partners didn’t know the music or the dance style, so it was completely random, just like it would be if they were real professional ballroom dancers. While Leah Remini promptly walked out when the danced was explained to her, others were excited by the idea of a little improvisation.

“It was fun!” Snooki told E! News of the Switch-Up Challenge. “It was a little scary at first but once you get in the groove it was great, it’s just dancing.”

Pretty Little Liars star Brant Daugherty also had a blast with the surprise challenge.

“It was a good time!” he said. “Really all you can do is have fun with it. There’s not a lot of technique you can employ, you just have to go out and move to the music.”

But the star who enjoyed the challenge the most? Comedian Bill Engvall, who took the opportunity to have some fun with his partner, Emma Slater.

“Right before, I looked at who was in our group and I thought, everyone here is a dancer, so I looked at [Emma Slater] and I said, ‘If the right song comes on, my shirt is coming off!’” Bill said. “And literally as the song came on I grabbed it and her eyes got big and then she started laughing. I have had so much with this and she has made it twice as much fun.”
