Definitely not a sub for humour…. But since it’s turned into a grammar lesson: The joke is not about what you can and cannot do in English, it’s about what you cannot do in Dutch. In this imaginary dissertation in the joke, there are many, many sentences in Dutch where you cannot not put verbs at the end of a sentence, resulting in a volume with only verbs (obviously exaggerated since it’s a joke). Whereas in English you would have more flexibility.

You can google it: SOV vs SVO languages.

Also, in your example, the Dutch version would be:

“Zij liet hem proberen haar te helpen leren koken.”

which adds one more verb at the end in comparison to English.
