Always trying to get a quick buck, he always set up scams to get money from the Cul-de-sac kids in an effort to escape the poverty he spent his whole life in. He was born in New York but eventually moved to Peach Creek during the Great Depression era. Purgatory would also explain Plank's occasional sentient behavior, which is most notably demonstrated in the movie.

He took his friend, Plank, with him in the afterlife since he was the last thing that he saw in life before he died. He died in 1922 after fighting a long battle with tuberculosis, 6 years before the discovery of penicillin. Having no friends, Johnny took a marker and drew a face on a piece of wood, and dubbed it Plank.

Rolf died around 1903 when his family's farm animals stampeded and trampled him. His family had moved to Peach Creek in order to establish a farm on its land. Rolf arrived first from the 1900s, the theory goes.This would explain why the year for the show is very hard to pinpoint, with multiple anachronisms present, and also why there aren't any adults in the show (although you do catch a glimpse of one every now and then). According to the theory, the children of the cul-de-sac each hail from different eras spanning the early 1900s to the early 2000s.

This theory posits that the kids who inhabit the Cul-de-sac are actually dead in reality and that the lives they lead there actually take place in a purgatory-like setting.
