Check out the first minute of "Half Nelson" with Ryan Gosling...shows him in white cotton briefs, right off the bat, also his bare feet, for those who like feet.
Then, when he walks in his bedroom to cut off the alarm, check out the MASSIVE bulge in his underwear. I must have rewound the clip a dozen times. The dude looks like he's seriously endowed.
Great movie by the way. For those that have netflix, it's available for instant viewing.
