Benny and Spot are two rubber fish I used to keep in Arthur.

Spot was a white fish with gold spots.  The only use this fish ever had was when a Twit would come up and take it out of Arthur and announce, "Look everybody!! I'm a Spot remover."  That worked only once.  That was about it for Spot.

Benny on the other hand was a complete success.
One day when Lord Percival had hurt his leg and needed to use my snob stick for the day I was stuck without one of my greatest props.  Until I discovered Benny.  Benny was supposed to be used for Fish Flick, a game despised by the owners.  Instead of using him for that, I spent that day interviewing people with the fish using it like a microphone.  Halfway through my interview, I would ask the question, "Do you know that fish don't have ears?"  When they would reply yes, I would ask them why they were talking to it then.  Conversation would ensue into pretty much anything, but the gag worked so well I kept it.
