Pickle Pup Gets Mangled

I worked on a movie I'll call "Pickle Pup."   My job was to blend computer characters (and their shadows and reflections) into live action scenes.  As the show neared completion, someone sent out an email asking everyone who worked on the show to sign the official poster.  It was going to be a gift for someone.
Most people just signed their names, but some added sketches of the title character.
I decided that's what I'd do too.   I liked to draw, right?   Never mind the fact I did absolutly no drawings, character design, or animation for the movie.

I planned to draw something like this:

What I really drew looked like this:

Arrrgh!   It might have been okay as a doodle, but compared to the professional sketches on the poster, it looked amateurish.  As in "I can't draw and am not aware that I can't draw."  And it was right next to my signature (which in a state of cockiness, I'd made rather large!)
I tried to fix it.

Soon it looked like this:

It was a mess.  What was worse, I was holding up the line.  People behind me (including people who got paid to draw cartoons) were getting impatient.  And wondering what the hell I was doing.

There was no saving the drawing.  It was a smeared, mangled train wreck.   I tried to blot it out into a stylish wedge of black:

The result was as stylish as a mustard stain.   Right next to my name.
I should have blotted that out too.
