Temperatures between two of the world's rugby heavyweights, New Zealand and Ireland, are set to flare not only on the field but in front of the television too.
So in anticipation of the chaos set to ensue on Saturday night, Air New Zealand has released a useful safety video for the Irish.
"Why is the World Cup is still pandering to the dance?" MacKenna asked.
"That's unfortunate as New Zealand are justifiably big-headed enough without a massaging of their already massive egos."
Well, it's going to happen whether you like it or not, so strap in and stay safe!
Tip 2: Store handheld electronic devices away
Pretty simple one this - don't be throwing your mobile phone or tablet device around in a hissy-fit. We wouldn't want you breaking anything.
Tip 3: Stow away young children
"Language might become a little colourful," the Air New Zealand attendant said.
This one covers both New Zealand and Ireland fans, as yelling, kicking and screaming is likely to occur from avid rugby fans from both nations.
Tip 4: Stick your heads between your knees
Only in emergencies, or when blinding speedster Sevu Reece dots across the chalk for the first try of the match, should you enter the emergency position.
But if it gets all too much and you start hyperventilating, maybe break out a paper bag and start breathing to calm yourself down.
In the safety video, Air New Zealand said an oxygen mask would fall down but you would think this is unlikely to happen in most Kiwi lounges.
But remember, the All Blacks are comeback kings, so don't stress too much if we find ourselves behind with limited minutes to go - remember 2013 in Dublin.
