These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Awesome: The entire film seems to be an attempt to consist of nothing but attempts at this. Almost any scene could be the climax of a slightly more rational movie.
I go with either Smith nailing DQ WHILE killing baddies; the parachute gun-fight; or Smith's finger-bullets
I vote for the spanking scene.
Crowning Moment of Funny: Quite a few in the movie. This troper's personal favorite is when Smith conks one of the mooks by shooting the back of a filing cabinet and smashes it into his head. Even Oliver seems to find it amusing.
Memetic Mutation: The sex scene is by far the most well-known scene in the movie. Many viewers who watch the scene on video hosting sites have no idea what movie it's from. They just know that it's an absurd[ly awesome] sex scene with Monica Bellucci in it.
