Adult Swim series Rick and Morty and Disney XD series Gravity Falls have not shied away from using Easter eggs in the past. But could there be a crossover between the two shows? Fans would like to see Rick and the Smith family's interaction with Dipper, Mabel and Grunkle Stan.

Gravity Falls creator Alex Hirsch himself has voiced a character in Rick and Morty and that show's creator Justin Roiland voices Blendin on the Disney show. Fans also noticed the hidden references between the shows, like a tiny Bill Cipher image hidden in a Rick and Morty episode.

Alex Hirsch talks about the possibility of the two shows existing in the same universe in an interview with Entertainment Weekly. "There was a time when Justin and I were both working in the same tiny office for the Disney Channel. We both dreamed one day of having our own weird TV shows, and we would talk about ways in which we would childishly abuse this power."

Hirsch explained, "For some reason, the universe has blessed us with our mad wishes, and it occurred to us — let's start doing things that nobody else does, that maybe you're not supposed to do. We started putting little easter eggs in our shows that sort of connected the two. Our motivation for that is primarily to freak people out and blow their minds. The impression of a grand brilliant design is probably more something that the fans have invented."

When asked about the possibility of a crossover of the shows, Alex dished, "I remember when I was a kid, whenever you'd see cartoons cross over with each other, it always ranged from a delightful, magical surprise to a cynical, annoying cash grab."

"So far, we've found that these little winking nods between our shows strike the right balance. I can't say whether or not there will be more, but I can say that we like to confuse and amuse people so who the hell knows," he teased.

Gravity Falls season 2 pre-finale titled Weirdmageddon 2: Escape From Reality, will air on 23 November on Disney XD. Rick and Morty will return with its 3rd season in 2016.
