Urban legend creature, said to take on the form of a rabbit, from the magical land of shroom. The only known proof of Jack Bob Livingston's existence is by playing side B of certain 70's rock band albums backwards on a record player. The record is played in reverse until an eerie screeching rabbit can be heard crying "shroomsss".
"Dude, are we trippin our faces off, or did we just hear Jack Bob Livingston?!"
