What is the verb funny card made Hal smile?

This sentence is grammatically incorrect and doesn't make sense. Here's why:

* "Funny card" is a noun phrase, not a verb. It describes the object that made Hal smile.

* "Made Hal smile" is a verb phrase, but it's missing the subject. We need to know what *made* Hal smile.

Here's how you could correct the sentence:

* "The funny card made Hal smile." (This clearly identifies the subject, "the funny card", and the verb, "made Hal smile".)

* "Hal smiled because of the funny card." (This changes the sentence structure but conveys the same meaning.)
