Adrian Edmondson’s upcoming, and much postponed, ITV1 sitcom, Teenage Kicks (currently due to air Friday March 28 – but that could all change) is an old school, broad-brush effort. And, here’s a thing, it features a Chinese, Star Wars-loving nerd called David (Jonathan Chan-Pensley). There’s a bit where one of the Caucasian characters takes the piss out of his accent, and gives it the full-on Charlie Chan. Is that okay, now?
