I want to go shopping!

It's so unfair, Mothers' Day is this weekend and Mommy and JerJer say that I'm not allowed out to go shopping unless one of them is with me. How am I supposed to surprise Mommy with a new mousey-poo or something if she has to come with me when I get it?
I could go with JerJer, but I doubt he even knows where the mousey-poo shop is because he is a boy.

Maybe I should get her some of the red stuff that she drinks that smells kind of like my puke. I know she likes that. Or I could get her a nice box with a plastic bag inside of it, everybody likes fun toys like that!
