LOL - Brian and Justin competing for attention and the Best Lead Actor in a Drama - hadn't thought of it that way before, but I will every time I watch this now. :)
I can think of many diner scenes I love. One is at the end of 120, when Justin reports back on his night with the trick after being crowned KOB. All the guys are there - even Blake, all welcoming Justin to the table ("Hail to the king!" hee), and watching Brian's reactions - and Michael getting the reference when Justin says "I told him he could see me in his dreams."
And Brian's look when Justin says this (see icon). *melt*
