Simpson was way too much of an airhead for Nick to deal with. I'm not just talking about the "is this Chicken of the Sea tuna? or chicken I'm eating?" deal. She's done other really dumb ass stuff, and for an adult? one has to wonder...what's doing on in her brain that's malfunctioning. The death of an only brain ell is a terrible thing to watch. Nick is SO much better without this no talent.
