to buffoon and cartoon yourself

(in Russian изображать: конкретно испоганить и испохабить образ и подобие по которому вас создал бог)

for a rational and pragmatic person, neither a comedy actor nor a clown by profession, to make a buffone of one's self in public.

even if you may be a Jim Carey or Harry Houdini by profession, the phrase to buffoon and cartoon yourself isn't supposed to be part of your vocabulary, at least when you are in civilized society
