Amy Sedaris guest stars on Oprah
(In a hilarious skit with Jon Stewart's "Good Time Van," a parody of Oprah's Wildest Dreams Bus)
Amy plays a Starbucks worker who wrote to the show and receives a visit from the Good Time Van. She goes batshit, quits her job, then finds out that she only won a ticket to see "Mamma Mia," which she'd never even heard of.
