A somewhat self explanatory question, what makes mess in a big red nose fun for you?
Personally, I adore the goofiness of it, it's fun to let loose by laughing. Eve adding gags or self inflicted booby traps before a slopping, fun stuff like that! As well as that, making a big show out of the slop is fun as well, whether it be performative grossness or jamming up the delivery!
