I am terrible for this. Scooter must have at least 10 nick names. I'm suprised he has any idea what his name is. Some of them are Scootie, Scooboo, Scoots, Scootie-pootie, Big guy, Scoo, Orange etc.
Clyde doesn't have as many, I guess because his name isn't as rhyming as Scooters.
Don't even get me started on the dog Pugsley. Every member of our family has at least 5 nick names for her. And she wags her tail for every one.
