It might be good to know that Cannell died in 2010 of melanoma, a change of color to the skin. Early additions had Cannell smoking a pipe while typing on the typewriter; which later became discontinued as Cannell quit smoking.
Most of the early additions had Cannell wearing a sweater while the later versions sported him wearing a polo shirt with the collar stuck up. Shows with this logo were The A-Team, 21 Jump Street, The Greatest American Hero, and several other 1980s shows.
On Family Guy,We see Peter typing on a typewriter,then he throws the paper.
We don't know about The Simpsons.
One YouTube variant has someone typing on a typewriter then he throws the paper.The logo is in reverse and the paper hits his face.
Scare Factor 😈Edit
None to low.
The logos music and video can be hard to forget. It could either relax you, or scare you.
