Many people under the age of 30 have never used a landline, let alone a payphone. Stephen Colbert took a random young person from his audience outside and taught her how to use a payphone for the first time. After spraying the phone with disinfectant and handing her some quarters (“Have you ever seen these before? They’re like Venmo you can touch.”) Colbert gives her step-by-step instructions. Unfortunately she doesn’t know any phone numbers, so Colbert tells her to call the number of the pizza parlor right next to the phone. Then Colbert has her call an operator and whispers into her ear what to say.
