Robin: That really wasn't my fault. I wouldn't have walked in on Marshall if it weren't for Lily. Hey, think about it.
[flashback to Ted and Robin eating as the walk down the street:]
Robin: Hey, what's going on here?
Ted: Oh, looks like they're camping out for something.
Robin: Yeah, but for what?
Ted: I don't know. Usually there's a Stormtrooper or Klingon in line to give you some indication. "Annual wedding dress blowout. Designer sample dresses up to 90% off. Doors open tomorrow, 8:00 a.m."
Robin: Oh, my God. Can you believe what some nut bags will do to save a few bucks?
[cut to the gang at MacLaren's:]
Lily: We have to camp out.
