Quote from Ted in Desperation Day
Lily: You brought an overnight bag? Ted: You guys said I was definitely going to spend the night. Barney: We said you were going to have sex. We didn't say, "Bring a carry-on." Robin: So how did Zoey react? Ted: She thought it was presumptuous and asked me to leave. It's- It's not like I brought a ton of stuff. Robin: Were there slippers for the morning? Ted: Not slippers, exactly. [all groan] They're called British morning socks.
