Another one - we just watched it on European-Timed Marathons - at the end of 307. Brian, ever-observant of Justin:
Someone didn’t sleep at home.
Justin: What are you, a detective?
Brian (not managing to conceal his satisfaction at the apparent turn of events): No. It’s just the same stunning ensemble you wore yesterday. ... Do I detect a discordant note in Loves Tender Refrain?
Hee. Really - Justin's sad, so this probably shouldn't feel so good - but knowing what's just around the corner, it so does!
Add to that the fact that Ted's not going to jail - because Brian came through for him - it's definitely one of my happy diner moments. :)
