Credit for this one goes to Tye Havey, our partner who oversees Wright Engineers' two Arizona offices. Here's the email exchange:
Tye: Cartoon Idea: Sometimes I walk quietly - or come in through a back door - or forget to tell someone when I'm coming or going. We've started calling me a 'ninja-neer'. Seems like it could be adapted for a good cartoon somehow.
Me: (with cartoon attached) The fruit of your inspiration. He does sorta look like you.
Tye: I love it. And yes, it looks a lot like me in my pajamas :)
All I know is I wouldn't want to mess with an engineer with serious "plan"-chuck skills.
