I couldn't watch the clip until last night, so wasn't sure what ya'll were reacting to. Didn't realise it was that skit from last weeks SD.... I hadn't really paid it any mind; deeming it just a light-hearted one-off clip born of Truth's larking about backstage.
As for the question of WWE reinforcing racial stereotypes and such... It really didn't strike me as scripted or instructed to him... More like he was overheard/seen messing about and was asked/told "That was funny - Will you do that on cam for TV"?
