I don't have a best scene, but fav two scenes because of the irony.
When Randal is talkin to LOTR guy about sam busting a nut in frotos mouth before the 20 different endings of LOTR, and that would be academy award type ending.. Then when they are in the jail cell and Randal and Dante are all mad at each other and it turns into a mega emotional gay fest where you think any minute they will start blowin each other, while JAY makes references to this, and then there is a 10 minute prolonged ending.
Great Irony, Smith is a genius.
