Shawn describes a famous past case of the The Yips suffered by Yankee 2nd baseman Chuck Knoblauch who suddenly began consistently overthrowing first base, one of which sailed into the stands and hit sports commentator Keith Olbermann's mother in the face. That story, while sounding like a classic Shawn Spencer exaggeration, is 100% true.
When Shawn calls for a toast to respect the other team, Carlton is actually toasting a salt shaker.
While restaging the crime scene, Shawn tells Gus the shooter held his position for exactly 26 seconds, because that's how long it took them to sing Happy Birthday. It actually did take them 26 seconds.
Shawn's jersey number is #44, the same number as on the (first) football jersey he wore in the previous season's episode, "Any Given Friday Night at 10pm, 9pm Central" (2009).
One of the comparatively few episodes to use the alternative theme song that starts with the verse rather than the chorus.
