Here's an obscure one that I have only encountered in early Golden Age comics: the German or pseudo-German accent that includes a prominent use of the prefix "ge-" as a word modifier, in the same way that a bad French accent might append "la" or a bad Russian accent might add "-ski" to the end of words.
How widespread was this? Did it exist outside of comics? No clue. How widespread was it within comics? That we can attempt to solve by gathering examples here. Perhaps some kind future cultural historian will be able to take the evidence thus presented and rediscover this lost stereotype.
