Quote from Lily in Mary the Paralegal
Marshall: [telepathically] Lily, I know you're asleep, but I have to tell someone this, and we tell each other everything. So, here it goes. Mary's not a paralegal. She's a prostitute. Lily: [waking up] Mary's a prostitute? Robin: What?! Marshall: Barney paid for her. Lily: Is that true? Marshall: We were having a conversation about prostitution, and then Barney calls her up and then she shows up at the bar and now she and Ted are upstairs. Robin: Okay, seriously, what is going on with Ted lately? Is he having a nervous breakdown? Lily: You know, Barney, for anyone else, this would be a new low, but sadly, for you, it's just a new middle.
