(Just a short post now, as I've got a busy day ahead of me!) In a Season 3 episode of Family Guy, Buster's dad Andy Capp appeared in the Drunken Clam, challenging Peter to a game of Darts! It was only a short, 15 second clip but he appeared none-the-less! Sadly I couldn't find a better quality video, but here it is for you too see!
Also on YouTube are a few animated Andy Capp stories. They're only about a minute long and no way near as funny as the strips! Here's one, there's four in total!
