Filler #71519 was a very influential filler video created by Ophios back in the summer of '08.
This video became extremely popular as soon as the video responses came pouring in. Eventually, it became its own fad.
The video starts out as if it was a normal day for "Jay Sherman", the main protagonist in the animated sitcom series The Critic. Throughout the video he is bombarded with very annoying phone calls varying from video game references to lines from other TV shows.
Status on the fad
Newcomers still make responses.
