In the second panel of today's strip, the third planet in V3's system was drawn by tracing the center hole of an extra copy of the Beach Boys' mid-70s top 10 hit version of Chuck Berry's "Rock And Roll Music" (with "The TM Song" on the flip side) that I had on the shelf near the drawing supplies. Two days ago the planet was drawn (or at least part of it was) by tracing the outer edge. And it was also used on Sunday, where the outer edge was the rumormongers' planet, and the center hole was the gas giant off in the distance. The 45 was not harmed in the production of any of these strips. (Though like I said, this was the extra copy - a little worn. I wouldn't have used a good one for this!)

...In case anyone was wondering!
