(back to Lily and Marshall)
Lily: Man, Ted's right, it's tough out there. A chick. Barney: Magic phone, guys. For what? Happy Valentine's Day. I didn't think you'd bring a date. Robin: Don!! The deadline for Marshall and Lily to find me a wife. We'll double date on Valentine's Day.
Plan: A: Ted; Q: Who allows Lily and Marshall to arrange a date for him? A: Robin; Q: Who foolishly consents to attend a Valentine's day party given by her deeply inappropriate co-worker, Don Frank? A: a 'magic' phone; Q: What kind of phone does Barney have? Summary: Ted abdicates responsibility for finding a Valentine's Day date, and allows Lily and Marshall to "arrange" a date for him; Robin foolishly consents to attend a Valentine's day party given by her deeply inappropriate co-worker, Don Frank. Barney has a 'magic' phone but can't stop answering it.
