Barney: Yeah, bait is tricky. It has to be something interesting enough to get the girl upstairs, but not so interesting that it overpowers the night. [v.o.] I found that a slot machine was too fun. And a trampoline turned out to be too dangerous. But then I found the perfect bait. A teacup pig.
Ted: A teacup pig? Who's that working on?
Lily, Robin & Marshall: [high-pitched] You have a teacup pig?
Ted: Can I borrow your teacup pig?
Barney: Yes, you can borrow my teacup pig.
[cut to Ted with Tiffany in his apartment:]
Tiffany: You have a teacup pig? Oh, my gosh, I can't believe you have a teacup pig.
