I didn't find it funny. Right from the start the host goes straight into mocking the subject so you know already his perspective and what he is trying to acheive. It could have been interesting if the subject was taken more seriously and comedic value could have still been gotten from the responses of those interviewed but we were constantly distracted by the hosts acting and trying to be funny.
It seems like they wanted to make a Borat style movie but just weren't clever enough about it.
