Headscratchers / Camp Lakebottom

• In "Camp Plantbottom" why did McGee and Suzi's parents send Suzi's birthday present to McGee instead of just sending it straight to Suzi?
  • Maybe they wanted someone to give it to her personally and only McGee could do that.
  • It'd certainly explain why they send McGee's stuff to Suzi.
• Is McGee supposed to be his first or last name? As a first name it's a bit weird but as a last name it's equally weird that everyone he knows calls him that, including Suzi.
