No sure this really counts, but it happened on the Curious George cartoon on PBS kids. I just caught the tail-end, but George and the Man in the Yellow Hat help save his cousin(?) uncle(?) Tam's castle by finding the deed and delivering it in the nick of time by wrapping it around a golf ball, thus hitting several Scottish cliches in short order (castle, golf, kilts, possibly Stevenson's Kidnapped). Wish I had seen the whole fifteen minute storyline.

Both the Man in the Yellow Hat and Tam are kilted (with fly plaid no less), though both kilts seem to be essentially solid color (the Man's kilt is yellow, but there's no strong overcheck, just a kind of hinted at darker yellow to suggest a tartan).

Don't think it'll get my son to ask for his first kilt, but I guess you never know!
