35-year-old Yi Fu of Chengdu, China weighs at least 265 pounds . . . and it's not muscle. Unfortunately for him, his delicious chubbiness is pretty bad for his attempted career as a cat burglar. Yi broke into an apartment complex to rob the place earlier this week . . . but some people woke up and started chasing him. He ran to the elevator, but it was broken, so he tried to escape by climbing through a narrow shaft in the ceiling. And you can see where this is going. Yi got STUCK halfway in . . . his head and torso were in the shaft, his legs were dangling out. He was stuck for EIGHT HOURS before firefighters could get him free. And once he was finally out of the shaft, he was arrested.
