Are You Contagious?

"We're going in it baby. We're just starting," Zach says as he prepares to go on the show. "I shouldn't have been with you Thursday or Friday, but I had to have been there." He's taking Z-Packs for a chronic cough and an antibiotic that makes him contagious. The episode airs at 8 p.m. ET Monday through Wednesday; watch back next week for another installment.
