Brian has just turned down a trick's offer of sex in the bathroom at Woody's...
Trick: You suck!
Brian: Only those worthy of my expertise.
Michael (at the same time): No he doesn't.
Brian: Of course I do.
Michael: Stop it, Brian. We all know you're the ultimate top and they don't suck cock. I know you; you've never sucked cock.
Justin returns to their table with a round of beers in time to hear Michael's speech: He sucks mine every morning... and afternoon... and night... sometimes more.
Michael: Bullshit!
Brian: Like I said, Mikey, only those worthy of my expertise.
Justin grins brightly, wagging his eyebrows at Brian.
Brian grabs Justin and heads to the bathroom saying he needs protein.
Michael pouts and crosses his arms.
The trick slinks away.
