I always found the Oreo Twitter to be really dumb. It's one thing to create a Twitter based on a character (Goddamn Batman, Voldemort, Drunk Hulk, the various Dalek Twitters), but those are actually funny and they can normally speak English. Noah made an account for his dog, and it talks like a baby, and it's not funny.
If it HAS to speak English, talk normally. This baby shit is annoying.
Looking back, the Oreo Twitter was likely another cry for help.
On RLM: Another issue with this is context. There was another recurring sketch called "Spooning with Spoony" where various people wake up next to Spoony after being raped, all while he conducts a talk show. The deal here is that the people agreed to this sketch (plus, Spoony didn't even write it, the Nostalgia Chick wrote the first one and the Critic wrote the second). What the Twitter issues are is that Spoony acts like a total perv to these women without their consent. So he comes off like a creep and people don't like that.
