Due to scheduling and availability conflicts, Shearer decided not to participate in "The Simpsons Ride", which opened in 2008, so none of his characters have vocal parts and many do not appear in the ride at all. In a 2010 interview on "The Howard Stern Show", Shearer alluded that the reason he was not part of the ride was because he would not be getting paid for it. Similarly, Shearer was unable to appear in the "Family Guy" crossover episode "The Simpsons Guy" due to further scheduling conflicts. Therefore, his characters are again mute. When asked about how he felt about the crossover, Shearer replied, "Matter and anti-matter."
