Just noticed this on a second viewing of last week's episode. If you're one of those who usually watches the episodes on tape and zips past the commercials, you may have missed this, like I did the first time. At about the 15-minute mark, there's a live-action joke "commercial" for Cherokee-hair tampons. Basic script: Exterior yard shot, mom & daughter talk, "heavy flow days," etc-etc-etc., look new natural tampon, ooh-ooh, and it's even recyclable as a _________ <--[spoiler omitted].
It's not especially clever or falling-down funny. (Falls way short of the only other such gag that comes to mind, the live-action Mr. Hankey ad from long ago.) I just felt I should mention it for the benefit of the compulsive DYN cataloguers.
