Here's a curious exchange between Welles and Mel Blanc from the G I Journal series (from Welles' period as radio comedian.)
I suspect that laughing at someone's stuttering problem probably isn't funny anymore, so maybe this is more an example of comparative historical anthropology than comedy. (To contextualize, at the beginning Welles is thanking Faye McKenzie for her song, and Earl Carroll owned The Earl Carroll Theater on Sunset Boulevard, which was famous for its showgirls.)
