Lily: That's awful. You realize you broke her heart, right? She's inconsolable.
Barney: Why would she be inconsolable? Lorenzo's balloon won't disappear over the arctic for another week. She would be upset only if someone told her it was a bunch of lies.
[flashback to Lily and Shelly talking at work:]
Shelly: It was all just a bunch of lies?
Lily: It was all just a bunch of lies.
Shelly: The balloon expedition?
Lily: Lies!
Shelly: The man-made island shaped like his face off the coast of Dubai?
Lily: Lies!
Shelly: Finishing 3 in laser tag competion?
Lily: Li... Actually, that one's true. I went to that.
Shelly: You went to the Vatican?
Lily: Lies!
