Ernst. This is the Van that Dad Cleaned

This is the Van that Dad Cleaned is a children's book by Lisa Ernst, with art by the author (presumably; the artist is uncredited), published in 2005. It is available at the Internet Archive.

Here is a YouTube read-along:

The story starts with a clean van, and then a girl and a boy, with a toy; there's also a baby all forlorn (an echo of the classic Jack), and then ketchup that is airborne (repeated rhyme, also like in the classic Jack), with more rhymes in -orn (just like the classic Jack)... the result is a mess, but this time it is the kids who clean up the van!

This is a fun book, and the way it plays with the format features of the classic Jack is very charming!
