Okay I get this merit badge -- I did a few guest comics for others back in the last century.  The main two I remember (fondly) are one for Chopping Block and one for GPF.

I just found the GPF one -- it was a joke about patents!  Ha, perfect for GPF.  And jokes about patents are just as relevant today as they were in 2002.

(Can't find the Chopping Block one on google though...)
