This past weekend, 'Harry Potter' actor Daniel Radcliffe appeared on the popular comedy series Robot Chicken in which he voice-acted the parts of an American calling out for "Kool-Aid" and a disgruntled Thomas the Tank Engine.
You can see a video of Dan's performance right here, but be warned, "Robot Chicken" contains language and themes appropriate for mature audiences only.
Adult Swim's Robot Chicken, a brainchild of Family Guy's Seth Green and producer Matthew Senreich, is a stop motion and claymation powered program on Cartoon Network that often parodies pop culture, obscure 90s cartoon shows, and anime series. For it's humor and violence the show is intended for mature audiences.
Daniel Radcliffe isn't a stranger to voice acting in a comedy series - a few years ago he lent his voice to an Edward Cullen look-a-like character in Fox's The Simpsons, during their Halloween special.
