The ytmnd wiki says moses and caesar are just Debra's pets...the number is real, i checked google..but..why would a guy answer the phone if he aint caesar? he must be MARK!! or..debra knows we're on to them and plays a trick..OR..its just her neighbour named caesar..

umm...you know, i noticed that the phone number in the gif kept changing, especially the last four numbers. Can you point out which is the correct one?
