just saw snow angels SPOILER!

In the scene where Annie and Nate are in the hotel room lying on the bed; could someone please tell me, what was up w/Nate's underwear?!?!? I was eating while watching the dvd I began to choke on my food when I saw Nate in a pair of "satin" like bikini underwear. Did anyone else find this scene equally hilarious and repulsive? Or was it just me?
