A few sales gigs ago the company I worked for had this cool plugin to Salesforce that when you closed a deal it would attach a YouTube URL to the win email and play it on the sales dashboards in the sales offices.
Each sales person would choose a 'Win Video', and after a while you'd get to know each video by which seller had closed.
It added fun and good vibes to the sales floor and accompanied the 'GONG'.
My video was always the scene from Entourage where Johnny Drama has gone out into the desert and gets the call from the others that he got a new role and he drops to his knees and says:
"thank you god....... VICTORY!!!!!!!"
What's yours if you have one? Or hypothetically what would yours be?
