An often-made reference to a segment of the WTF podcast, hosted by comedian Marc Maron. Each episode of this podcast opens with Marc Maron talking/rambling/ranting about his life or any random subject he wishes to speak about (interspersed with ads for JustCoffee.coop or the like) before he gets to his main interview portion of the show.
Adam and Ben enjoy a few several minutes with each other at the start of each pod Maroning around with whatever comes to mind. This is also the section of the show that employs running segments like trading card opening or Bible Study. TGG Maron Opens typically have an air of spontaneity, and some are more successful than others, but they're always a fun warm-up for the main show.
