At the end of the episode, there is a possible shout out to the U.S. Acres episode "Temp Trouble" when Crash imitates the movie the girls were begging to see the whole episode making their mom confused. This is reminiscent of the scene at the end of said U.S. Acres episode where Roy and Wade imitate Aloysius, confusing Orson.
From episode 3:
Crash says "This is not a Lady Ga Ga concert!" when he fails at "Musical Introductions"
One thing that made Crash a bad coach is that he drew on people's faces when they were exhausted.note In the Pokemon episode "The Song of Jigglypuff", Jigglypuff does the same thing after exhausting people (or rather, putting them to sleep).
From Episode 4:
Crash mentioned that a girl was on his Fantasy Football team.
Crash uses a toilet for a bathtub like in the theme song. note This is a shout-out to a Have A Nice Day segment on All That where Leroy tries to send Fuzz away in a "puppet bath", which is really a toilet.
"And that's what it feels like to be an NFL Quarterback!"
