Because Scooter is peppy and funny and naive and a little sarcastic and has super cute glasses--oh wait, you mean in a general sense. I think in my case it has something to do with feeling sorry for them in their obscurity. For example: When I heard that Nigel had originally been the host of TMS, and was voted out for lack of charisma, I started kinda fawning over him and wrote as one of the core characters in my fan-fic. That's kinda a girlie thing though
. Still, it gives me a fun feeling of excitement pointing out characters in the new movie like Wayne and Wanda and Uncle Deadly who never really got there spot in the limelight before. Did you know Nigel originally had the whistling talent Walter is now famous for?
