This clip is from an episode of the No Such Thing as a Fish podcast, which is a very funny podcast about interesting and surprising facts.

This sentence is an example of a third conditional, which is used to talk about the hypothetical/unreal past.
The structure of a third conditional is: If + past perfect, would have + past participle
e.g. If I had studied for the exam, I would have passed. In reality, I didn’t study and as a result I failed the exam.
Notice the weak/unstressed pronunciation of ‘had’ as /əd/ and ‘have’ as /əv/ – this is common in third conditional sentences.
