There is absolutely no surprise on who gifted this to Norman. Though it's wrapped and boxed, once Norman opens the box and is greeted with a mug, it's obvious. Especially with the markings. One either side of the word Dad are two paw prints: both in red and very similar, though noticeably different. One squirrel paw and one rat paw.

Should Norman turn the mug upside down, there's a little note there too: "i know ur old but dang. other end yo :) love you".
