I see Channel 4 has been mucking about with My Name Is Earl again. It’s on Thursdays now, at 10.45pm, and this chop and changing is a real shame – the show is always worth a watch and remains reliably amusing viewing. This week’s episode looks like a real must-watch, guest starring as it does Napoleon Dynamite’s John Heder as a supermarket worker who trains Earl for a bagging competition. Go over the jump to watch the trailer.
