"Where's the snake?" - when you know you've got a long day ahead of you.
Personally not a big fan of reptile pets because they spend the vast majority of their time just staying perfectly still. I can get a model replica to do the same thing and then I don't even have to feed it.
Love it! A Ball will be my next snake - I have an Albino (Kia) Corn, she's about 4.5 feet, which is her maximum length, and likes to curl around my neck and watch hockey.
