- The credits of "Caffeinated Concert Tickets" and "Mordecai and the Rigbys" enlist that he appeared in those episodes, though he was voiced by S. Scott Bullock in the first and William Salyers in the second.
- Dude may be a reference to Spose - an American rapper, which in one of his music videos (I'm Awesome) he's seen wearing a hoodie with a baseball cap and a matching pair of white sunglasses. However, this may just be a coincidence.
- His cameo appearances are similar to Snail, a character from Adventure Time. Both make cameo appearances in several episodes, and both only had one role other than a cameo character. Both appear in almost every episode of their show. Only that Snail is possessed by the Lich and Dude isn't possessed by anything or anyone.
