Quote from Barney in Right Place Right Time
Barney: I did it and I still have 30 minutes before I'm supposed to meet Petra. Robin, do you have any concealer handy? I'd really like to cover up some bruises and razor burn. Robin: Barney, I hate to break this to you, but... Barney: What? Robin: Well, you did count Gaby Allan twice, but you also went from 138 to 138. You used the same number twice. Barney: Wait, so, that means... Pauline wasn't 199, Pauline was 200? Ted: Congratulations! Robin: Woo-hoo. Barney: No... That was supposed to be Petra! Petra was supposed to be 200! Gorgeous, feminine, "Doesn't wear a weight belt in bed," Petra!
