Oh, yes, I noticed those. At least in the eps I have at the moment, the first five. I'm sure that last one came from a later episode.
Odd that it's Donnie in those first scenes, 'cause he was always dissin' her. Guess guys will be guys. (No offense to the males on this forum.) I'm guessing they were in jokes, and I don't think kids watching would have realized the implications. We can have fun with them, though.
