Sometimes there's no better entertainment during sporting events than moments when things that were not meant to be heard are heard by everybody watching.
Or a ''Hot Mic'' as they're famously known as.
And fans got a doozie from the Boston Bruins and Chicago Blackhawks game this past Saturday when an attempted dump-in drilled an official. Linesman Kiel Murchison was caught on a hot mic dropping some foul language after MacKenzie Entwistle's dump caught him:
''Ah f*** off!''
Watch the play below, as probably anyone watching from home heard Murchison's displeasure.
