Quote from Marshall in Showdown
Marshall: [recording] Um, I thought since we're going to be apart for two whole weeks, I would sing you your night-night song. Night-night, Lily Night-night, Lily It's time to go to bed, oh, my silly, little Lily Time to rest your little head Sha-la-la-la-la Sha-la-la-la-la Come on, Ted. Ted: No, it's weird. Marshall: You promised. Both: Sha-la-la-la-la Sha-la-la-la-la Sha-la-la-la-la
