The Texas senator was taking questions from a packed room when a young boy named Hank stood up to ask his question.
When the mic wasn't working and Hank was too far back for the senator to hear, Cruz invited him to come towards the front.
Hank took the invitation one step further and walked up onto the stage. Cruz smiled, shook his hand and then handed his mic over to him.
"In 1992, Hillary Clinton said she didn't come to Washington to bake cookies, so why does she have so many waffles now?" Hank asked.
Cruz laughed and gave an answer that fired up his conservative base.
"My view on Hillary Clinton is I think she is running on an agenda of ideas that don't work," Cruz said.
