Old Man Marley is an immortal being who was "left unfinished by God". When he dies, he is rebirthed from his toilet in full health with all memory in tact.

It is implied in Season 2 and Misadventures that he went insane during World War 2 and began his never ending killing spree of anyone and everyone who tried to take away his standard way of life. Currently, while it's impossible for him to be truly deceased, he is trapped in his toilet pipes by hardened monkey feces.
