  • Barney explains to Ted the "Three Days Rule" to Ted, but will Ted take his advice?


    "The Three Days Rule" is a funny How I Met Your Mother episode. I love the beginning of this episode when Ted gets a phone number from a girl named Holli and Barney has to explain the "Three Days Rule". I love how Ted decides to text Holli instead and their text messages become very dirty. I love how it's revealed that Ted has a laugh for when he sees naked women. I love how we find out that Barney and Marshall have been pretending to be Holli, so all this time Ted has been having dirty conversations with Marshall and Barney. I love how Robin tells Ted about Barney and Marshall posing as Holli, so Ted decides to play with their heads and tell them that he had a gay sex dream. I love how Barney and Marshall argue over who Ted might be more attractive to. I give this episode a 9/10.
