The original had some funny moments but was pretty ordinary overall. You just know the sequel is going to suck in the most horrible way imaginable.
Having said that, some people absolutely love movies like this. I only wish I could be entertained so easily.
Run headlong into a brick wall. Repeat untill you forget why you're doing it. That should sort you out for enjoying anything. Either that or just drink untill you can't stand up.
I saw the trailer... it looked like Duece Bigalow 1, only the storyline looks retarded, rather than just stupid.
