"Gormandizing Greedy" is the second time in the series that a Smurf is shown taking off their hat. The first was in "The Smurfette". In this episode, Greedy is the one to do so.
The title of the episode "Gormandizing Greedy" is a wordplay using Greedy's original French name, 'Schtroumpf Gourmand'.
The foodball the Smurfs are playing may be a parody of baseball but with watermelons.
The title of the episode "Waste Not, Smurf Not" is a wordplay of the adage, "Waste Not, Want Not".
A similar-themed story in the Smurf comic books, "You Don't Smurf Progress", extends the idea of the episode "Waste Not, Smurf Not" even further when Handy builds robotic machines that do all the work of the Smurfs for them--until one of the machines becomes sentient enough to reprogram the other machines and have the Smurfs serve them instead.
