Barney : You can't call her, you have to wait three days to call a woman. That's the rule !
Ted : Barney, that rule is completely played out. Girls know exactly what you're doing. Hey ! I got a new rule, it's kind of crazy, it's called "you like her, you call her".
Barney : I'm sorry, can you repeat that ? I don't speak "I never get laid".
Ted : "The three days rule" it's insane. I mean… who invented it ?
Barney : … Jesus.
Marshall : Barney, don't do this. Not with Jesus…
Barney : Seriously. Jesus waited three days to come back to life. It was perfect ! If he had only waited one day, a lot of people wouldn't have even heard he died. They'd be all, "Hey Jesus, what up?" and Jesus would probably be like, "What up? I died yesterday!" and they'd be all, "Uhh, you look pretty alive to me, dude..." and then Jesus would have to explain how he was resurrected, and how it was a miracle, and the dude'd be like "Uhh okay, whatever you say, bro..." And he's not gonna come back on a saturday. Everybody's busy, doing chores, workin' the loom, trimmin' the beard, no. He waited the perfect number of days, three. Plus it's sunday, so everyone's in church already, and they're all in there like "Oh no, Jesus is dead", and then BAM ! He bursts in the back door, runnin' up the aisle, everyone's totally psyched, and for your information, that's when he invented the high five. That's why we wait three days to call a woman, because that's how long Jesus wants us to wait... True story.
