I think I would not rate that a failed call because, while it was a bit of a flameout on Wally's part, it was not boring. In fact, presumably without meaning to, it elicited both some of Tom's funniest apoplexies ("WHY IS IT CLEAR NOW??? IIIIT'S MUUUUFFFFLLLLED AGAAAAAIIIN!") and some of his deepest wisdom ("Yeah, fight, but fight for the right reasons." I enjoyed listening to it and therefore cannot really task Wally with derailing the show. In my listening history, psychodramas don't usually run this deep, at least with basically sympathetic callers. I would say give him some humiliating task--maybe an essay, like with Amadeus--and let the other bans stay on course.
