I could be wrong, because my memory is definitely hazy on the episodes these days, but I seem to recall there being an indication that Wayne Irig was a widower. At one point in GGGOH, Clark mentions wistfully that his wife used to make the greatest candy apples when he was a kid...and it does sound as though she's not around to make them any more. At least, that's how I remember it. You'd probably want to check out the script to make sure.
