Mac and Martin in “Unfinished Business”

I think my son's hair is dyed.

Oh, right. Well, have you checked to see whether his collar and cuffs match?

Martin, he's four years old.

Yeah, I know.

But if it is dyed, do you see what that means? Do you see what that implies?

Means he's probably quite vain about his appearance? Oh my God! He's gay!
