Overview: You have to wait three days from receiving a number to call the person.

Theoretical Origin: Jesus invented the three days rule by waiting three days between his death and resurrection. According to Barney, "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, "Uh, 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..."

Validity Score: [10/10] This theory draws from the fundamental age old question: WWJD (What would Jesus do?)
