Whistler

Whistler was a demon in the television series Buffy the Vampire Slayer. Despite his origins, he is a servant The Powers That Be who describes his duty as maintaining the balance between good and evil. "Whistler", is actually an alias, as his real name can only be pronounced by dolphins, which would mean it consists of a series of whistles and screeches. He appeared in the last two episodes in season two, and was portrayed by Max Perlich.

Although Whistler only appears in two episodes of Buffy the Vampire Slayer, he is surprisingly well-known by fans. His narration in the episode "Becoming, Part One" is especially well-known and quoted often:

"Bottom line is even if you see 'em coming, you're not ready for the big moments. No one asks for their life to change, not really.  But it does.  So what, are we helpless?  Puppets?  No.  The big moments are gonna come, can't help that.  It's what you do afterwards that counts.  That's when you find out who you are.

"You'll see what I mean."

Whistler was originally planned to serve as a sidekick for Angel on the Buffy Spinoff, Angel, but Joss Whedon cited schedule conflicts with Max Perlich's film career as the reason for replacing Whistler with Doyle, a similar character. Some fans contend that the "real" reason was a copyright issue with Marvel Comics, whose own character named Whistler is a sidekick to their "daywalker" vampire, Blade.
