- Drew Brees is the first real-life person to appear in Sibling Rivalries (although he looks nothing like his real-life counterpart in his first appearence). The next real-life person to appear is Eminem, who physically appears in "Not Afraid (Of Losing My Concert Tickets)".
- In "The McRearys' Halloween Special!", Gerry is dressed as Drew Brees for Halloween.
- He is incorrectly seen left-handed in the series, as he autographs a paper for Packie with his LEFT hand. The real-life Drew Brees is right-handed.
- Jason Parker is also a fan of Drew Brees. His trademark shirt is, in fact, a Drew Brees jersey.
- Non-chronologically, "Drew Brees" were the first ever words spoken out loud in the franchise, as Gerry had the first lines in "Hello, Wisconsin!" not counting Packie's narration in his thoughts.
- Gerry started mentioning Drew Brees less often from Season 4 on.
