Perhaps you remember this scene from Bill & Ted’s Excellent Adventure:
Bill: The truth is, Wyld Stallyns will never be a super band until we have Eddie Van Halen on guitar.
Ted: Yes, Bill. But I do not believe we will get Eddie Van Halen until we have a triumphant video.
Bill: Ted, it’s pointless to have a triumphant video before we even have decent instruments.
Ted: Well how can we have decent instruments if we don’t really even know how to play?
Bill: That is why we need Eddie Van Halen.
Ted: And that is why we need a triumphant video.
Both: Excellent! *air guitar*
