Lily: Ted? What the hell are you doing in my room?
Ted: Uh...
Future Ted: [v.o.] There was an explanation. You see, after Marshall got off the phone with Lily, he had called me.
[flashback:]
Ted: [answers phone] Hey, buddy, what's...?
Marshall: Ted, I need you to sneak into Lily's room, find her phone and delete the last text she got.
Ted: Why? What's...?
Marshall: Ted, I need you to do this, no questions asked. And as we both know, you owe me a "no questions asked."
[flashback:]
Marshall: [answers phone] Hey.
Ted: Hey. Listen. I need you to do something for me, no questions asked, okay?
Marshall: What is it?
Ted: Meet me at the corner of 53rd and Eighth. Bring your drill.
[later, Marshall carries his tool box down the street as he passes a mail box:]
Ted: Marshall.
Marshall: What the hell? How did you...?
Ted: No questions asked.
[back to first flashback:]
Marshall: I broke federal law drilling you out of that.
Ted: Hey, I was a man in need.
Marshall: I know, you were a "Priority Male."
Ted: You said you'd stop doing that joke after the editor of Bazooka Joe comics rejected it.
Marshall: That man is a comedy snob. The point is, you owe me a "no questions asked."
