I am looking for a fix where Burt Hummel realises that one of Rachel's dads made the "fag" phone call. I remember that the glee club were doing a show for the parents and he overhears her dads being disparaging about the other kids and lays into them - quickly followed by everyone else. Also, Puck & Kurt were a couple.
Thanks in advance x
