Hello, fans of the show. I am enjoying mushrooms for the second (ish) time and I think it turned out well. There is a long explanation of what "morning wood" actually is at some point during the show. But that is for me to know where it is and for you to find out. (spoiler alert: it's not at the beginning). 

The episode artwork depicts a caving drawing of TSG smoking a joint and displaying "morning wood"
