The arms holding the Banana tablet in panel four belong to Ronnie from the webcomic Whomp! From the website:
It’s a semi-autobiographical gag-a-day comic that chronicles life’s ups and downs through the eyes of a big hairy guy who loves anime and McNuggets (yours truly, to be precise.)
I really enjoy Whomp! I think it’s a great comic with some terrific dark humor. If you get a chance I highly recommend checking it out. Ronnie is a fun character, and we’ll see more of him on Friday.
