Marshall receives a call from Garrison Cootes, a partner at one of the nation's largest environmental law firms.
The danger of a background check concerns Marshall, who fears that a college-era video of him streaking through Wesleyan calling himself "Beercules", which is now available online, could result in Garrison dropping the job offer.
However, Marshall ends up getting drunk and streaking again after inadvertently playing Edward Fortyhands with Pete, and thus another "Beercules" video is uploaded.
Pete's refusal to take it down prompts Lily to blackmail him with information that she claims to have received from women who dated him in college.
He meets Nora at a 24-hour diner, where he is forced to explain to her all the plays he ever made on women, one of which irks a woman in an adjoining booth who overhears the conversation; she turns out to be one of Barney's previous conquests.
Future Ted tells his kids that a person will know for sure about falling in love "pretty quickly and with absolute certainty."
