Even by the standards of the fixture, Saturday's Celtic-Rangers match witnessed a high degree of distasteful off-field shenanigans.
They haven't met in an SPL game in four and half years and some supporters evidently felt obliged to cram sixteen games worth of bile into ninety minutes.
Absence makes the hate grow stronger it would appear.
Disturbingly, there were images on Twitter of Celtic supporters hanging dummies with nooses around their necks from the upper deck of the Stand. One of the dummies wore a Rangers scarf while the other wore an orange sash.
It was accompanied by the a banner which read 'This is it Bhoys, this is war.
Many on social media have pointed out that the 10th September was World Suicide Prevention Day. It also came days after ex-Rangers striker Kris Boyd spoke about his brother Scott's tragic suicide last week.
Celtic supporters on social media have denied there was any link to Boyd in the display.
Another banner unveiled at the Celtic end bore the message 'Know Your Place Hun Scum'.

Elsewhere, videos emerged of Rangers supporters trashing the Celtic Park toilets while hollering out 'The Billy Boys'.
Rangers FC has released a statement on the matter.
The club's directors are fully aware of the disgust felt by Rangers supporters who were subject to a sickening and shameful display of outright sectarian hatred towards them. We also share the fans' anger and will be contacting Club 1872 as a matter of urgency.
The 'Club 1872' grouping mentioned in the Rangers FC statement are a Rangers supporters group who had written to the board about Saturday's events.
Club 1872 today called for Celtic fans to be banned from Ibrox. Their statement is aimed at the 'Green Brigade', a grouping within Celtic's support which they accuse of 'sectarianism', 'anti-semitism' and supporting 'active terrorist groups'.
They also accused the Celtic chief executive Peter Lawell of "cultivating" the Green Brigade.
Club 1872 has today written to the Rangers board requesting that they ban Celtic supporters from Ibrox until Celtic can prove they have taken substantive action against the Green Brigade and other overtly sectarian elements within their support.
The Green Brigade has been cultivated, encouraged and rewarded by Peter Lawwell and the Celtic board for many years. So much so that at the beginning of this year they received their own standing section within Celtic Park. This is despite regular displays in support of active terrorist groups, anti-semitic displays and sectarian displays.
At the Old Firm game on Saturday the Green Brigade displayed sectarian banners which read “Kill All Huns” and “Know Your Place Hun Scum”. They also displayed banners in support of the IRA. This follows on from similar banners at last year’s Scottish Cup semi-final.
"They were joined by other Celtic supporters, in a separate part of the ground, who hung effigies of Rangers supporters with their hands tied behind their backs and ropes around their necks.
These displays were disgusting, threatening, sectarian and criminal. The groups responsible are easily identifiable if the will is there to do so. The reaction of both Celtic and Police Scotland has so far been pitiful.
They have been joined in inaction by the Scottish Government, media commentators and anti-sectarian campaigners who are conspicuous by their absence. It would appear soundbites are only of value when those on the receiving end of offensive behaviour wear green.
The grouping did address the trashing of the Celtic Park toilets, urging Rangers fans to refrain from behaviour that would result in financial penalties for Rangers. They noted in passing that "this happens at every Old Firm game in Ibrox".
We would also remind our own supporters that damage to the toilets at Celtic Park will only see a financial penalty for our own club. The fact that this also happens at every Old Firm game at Ibrox is no excuse. Supporters should remember that in everything they do they represent Rangers and should act accordingly.
