Andy Earles hasn't called in a couple of years, so depending on which shows you've heard from the archives, you may or may not have heard him. Skag Winesack and Kevin were his major recurring characters. He never really "did" character voices, so his calls are pretty obvious.
I know feelings about Spike are pretty varied, but he's one of my favorite callers. As others have said, he really does bring out the best in Tom. And the best thing is that while Tom is making these hilarious speculations about Spike's life (how many pieces of cutlery he has, whether he's wearing an ankle bracelet, whether he's on a stolen phone line/internet connection, etc.), Spike just plows on with the most banal answers, as if he doesn't realize he's being made fun of. He's been calling forever and I honestly can't tell if he's in on the joke or if he's just amazingly oblivious. He's like Margaret Dumont in those Marx Brothers movies.
I'm also a fan of the creepy laugh he's been employing recently.
