I thought the final panel was less funny than several other bits. The dog? The food rapping? The fact that he's now Gabe and Tycho's son?
The problem I see is that he seems to be angling less for the job as a designer and more for Gabe and Tycho's (wait, are those their real names?) job as a cartoonist. One might worry that he'd have to be repeatedly told "No, sit down and fix the website, stop pitching us strip ideas"
I found a copy of the original job ad, btw:
