It wasn't the actual points he was trying to make that were funny but the sheer ridiculousness of certain situations he created. A couple of examples, without giving anything away, was the protagonist escaping the authorities by threatening to put his knee through a piece of art. Another was after being a murder suspect, instead of easily clearing his name, he blindly follows this women he just met all over Europe merely on a whim while being chased by the police.
Not to mention the standard cliche of the "bad guy" being an albino named Silas.
