Dimension traveling device

Stewie is a little genius! In this one episode, he created a dimension traveling device, him and Brian (of course) they started traveling through dimensions. like they start start of by going to a place only dinosaurs or a place where the Americans didn't drop the Hiroshima bomb so everybody is Japanese. Or a place where there is only one guy screaming compliments from far(lol! stupid) or other places where everybody is gay or something like. Until they come to this place where dogs rule the world and humans are pets, its the other way around. stewie was tryna figure out how to go home but Brian wanted to stay. So they wrestle for the remote and it breaks. After that they went to they're house. they found stewie(as a dog) and Brian(as a human) and he tells him how to go home because they survived the same experience. While they where going home, Brian(human) said i wanna go to the world where he can be someone and he jumps in the teleport at the last second. as soon as he gets there he gets hit by a car and dies lol.
