- “Wubba Lubba Dub Dub!”
- ―Rick's catchphrase
Rick appeared in a Simpsons couch gag before the episode Mathlete's Feat known as the Rick and Morty Couch Gag. Here, he was teaching Morty how to drive the space cruiser, which resulted in them crashing through the house and killing The Simpson family, striking the duo with fear. Rick immediately started blaming Morty for it because he was the one who was driving the space cruiser. He then helps solve the problem by scooping up the remains of the family in a vial and giving it to him along with their family portrait and uses the portal gun to open a portal there and sends Morty in to clone the family while he stays at the house to clean it up. However, he did everything but clean it up as he walked around the house, doing random things. He rummaged through their refrigerator and ate a doughnut. He also got some duff beer and drank some, but didn't like the taste so he poured some alcohol from his canister in there. He also collected things such as Bart's slingshot, Lisa's saxophone, and Marge's necklace. Ned Flanders walked into the house and saw what he did and so Rick had to freeze him with his freeze ray. When Morty returned with the cloning DNA, Rick was seen sleeping on the couch and was then woken up by him. Morty gave Rick a bag of mutated balls. Rick dumped them all out on the couch and turned up the thermostat which caused them all to mutate and grown into The Simpsons. However, something goes awry when they all end up being mutated, disgusting looking versions of them with Rick's skin and hair, as well as his bad belching habits. Rick then says that the reason for that is because his DNA got mixed into the vial from cleaning it with his own saliva. He then takes his bag of stolen things and he and Morty get back into the cruiser and fly off, realizing there's nothing else they can really do. He also states he'll be driving the ship this time, also consequentially killing Flanders by having his frozen body shatter from being knocked over by his taking off.
Rick is a tall, lanky old man. He has long legs and arms and is very skinny. He has dimly tanned skin and blueish gray hair. He has spiky hair on his head and a unibrow. His face is wrinkly as he has bags under his eyelids and a pressure fold above his unibrow that follows it's position and laugh lines on both sides of his mouth. He wears a white labcoat with a light blue green shirt underneath. He also wears brown pants, a dark brown belt with a yellow buckle, and black shoes. He is occasionally seen with some green splattered vomit on his mouth which is the result of him ODing from the massive amounts of alcohol he consumes on a daily basis, although this isn't always on his face but shows up mainly when he is drunk or after he throws up. Rick speaks in a very atrocious and rambling manner that is often times corrupted by belching and gagging, again this is due to his drug and alcohol addiction.
Rick is a genius scientist, capable of creating complex scientific inventions, including brain-enhancing helmets, dream-invading devices, portals to several different dimensions, and the world's first amusement park inside the body of a living human. His brilliance can be muddled by his jaded personal views and his alcoholic tendencies. Rick is easily bored and does not do well with routine. He has a tremendous ego and constantly drags his grandson, Morty, (and sometimes granddaughter Summer) on dangerous adventures across the multiverse. Despite this, he does genuinely love his daughter and grandchildren.
