A couple in North Carolina has found a unique way of protesting anti-abortion protesters by holding up humorous signs.

Every Saturday morning, Grayson and Tina Haver Currin from Raleigh, North Carolina, stand outside the local abortion clinic holding handmade signs such as "Bring back crystal Pepsi."

It seems the couple's intent is having the desired effect, with Tina saying, "we've been able to stop (the protestors) from harassing the families going into the clinic by turning our camera phones on them, because they don't want us to record them doing that. They'll put their signs away too sometimes."

The Currins say they were motivated to start their own protest to "combat the hateful rhetoric with humour."

"From my point of view, when we were driving by the first time, I looked over at Grayson and I could feel him bristle up a bit," Tina explained. "I was driving and I was like, "Don't yell at them!" I think that was the reaction we both wanted to have, but we knew that wasn't going to be productive. This appealed to us as a way to do something that isn't throwing up a middle finger and driving on by."

While the couple may look relaxed in the photos, Tina admitted she was scared every time they held their signs up.

"It's very upsetting; they say terrible things. I have a pretty strict no-talking rule. I don't really engage with them, but they engage with me. I try to smile and hold the sign," she said.
