In other words, any time you are on someone else's payroll being paid to pay attention to the business at hand, and you are zoning out, engrossed in the scribbles coming out of the tip of your pencil or pen, then those drawings are indeed Goofy Service Doodles.
Which reminds me...I think I produced two Goofy Service Doodle Books in the '90s. Both with very low print runs and long out of print. I really should take the contents of those two books along with the Heyoka ashcan and a whole bunch of other stuff and make a small press mini-collection of these odd and obscure drawings sooner than later.
And on a final note: Barack Obama has a totally cool comic book signature, don't you you think?
