Ted: I can't believe we lost her.
Robin: See, this is exactly why I'm never having kids. You can't let them out of your sight for even a second.
[meanwhile, in Marshall's office:]
Marshall: I can't find my file.
Lily: I pulled out "A" through "G." Ag! Aaaaggg.
[back:]
Robin: They just sit there with their stupid bottles.
[Lily is drinking a bottle of wine in Marshall's office]
Robin: They cry.
[Marshall gives Lily the bottle of wine back]
Robin: They spit up.
[Lily throws up in the trash can in Marshall's office]
Robin: And that's why kids suck.
