Admit it: you never thought you'd be buying a video with the word potty in the title. But it's been months, and while Junior seems to love his potty, he doesn't actually do anything in it. So you need some inspiration. Well, you've found it. The Once Upon a Potty video for him or her expands upon the popular children's book by the same name in two ways: there's a sing-along potty song and a 13-minute doctor's statement for parents. The director of child psychiatry at a prominent New York hospital will calmly reassure you that it's perfectly normal for Junior to be taking his sweet time letting go of the diapers, and that's worth a lot. And the animated retelling of Joshua's potty progress is good, too.

But it's the "music video" of the oh-so-catchy "Potty Song" that makes this half-hour tape. And just in case you aren't already singing the song in line at the bank or the grocery store, the thoughtful producers have included a lyric sheet for you. "Yes, I'm going to my potty, potty / Now, I'm going to my potty, potty....". Yes, there is a good reason why Once Upon a Potty remains a classic - it works.
