Quote from Barney in Third Wheel
Barney: [answers phone] Stinson. Ted: I've got a situation. Trudy is here, you know, the pineapple incident. Barney: You mean, the girl who chalked your pool cue and snuck down the fire escape. Respect. Ted: So, we're hitting it off and then her friend shows up and they're kinda competitive. I think the new girl's kinda into me. Barney: So you now have two on the line? Ted: And I don't know which one to go for. Barney: Go for the new girl. Given the choice, always party with Dr. Strangelove.
