This episode is infamous among those familiar with internet memes, as this is where Dr. Robotnik's line of "snooping as usual, I see," became immortalized as one of the most popular Internet memes to date. What makes it so popular is because of the emphasis Robotnik puts on "PING" in "Snooping" and "AS", putting them together as "PINGAS", which sounds like a male body part.
The PINGAS quote was later said by other Dr. Robotnik actors Garry Chalk, Jim Cummings and Mike Pollock, who said the quote in a Sonic Boom installment. Other voice actors who voiced quotable villains such as Richard Epcar's Joker from Injustice and Greg Baldwin's Aku from Samurai Jack said the infamous quote in videos made by Christian Frates. It went to the point where people sent petitions to Jim Carrey to say the quote in a future Sonic sequel.
