It all depends on how you look at it. Could be just a reference to fast ogive style nose cones, or maybe to a certain cartoon character in a clown suit.
well apparently I'm not the only one since the possible reference to a certain cartoon clown has not gone unnoticed. Extreme Rocketry must not be the only mag people around here read
Zippy Pinhead is not actually an obscene cartoon, irreverant certainly, although it's been published in questionable venues. Just to end this hear though I'm changing my screen name, or shortening it anyway.
I knew what your real intention was with your name. I just thought it was funny when I read it another way, I didn't intend to insult you or suggest that you should change it.
