Terrence Howard may be crazy, but it takes a truly insane person to nail an impersonation of him. Adding on that, it takes sky-high levels of both delusion and psychosis to do one while wearing blackface. Thankfully, Robert Downey Jr. fits that mold perfectly — and, wouldn’t you know it, he did an extended Terrence Howard bit while in his character from Tropic Thunder. It’s pretty spot-on — by which I mean he sounds completely batshit.
