Dave King threw the Hotline a hand grenade by claiming his prediction that Celtic would crumble is coming true.
The former Light Blue chairman lit a fuse by insisting their Old Firm rivals only have themselves to blame for a season which is unravelling.
John Charles, Falkirk, said: "King may live to regret his “fold like a pack of cards" statement as I am pretty sure Dermot Desmond will make sure of that. King should concentrate on his own club. Celtic know they are a big club, Rangers think they are."
Richard Wharton, Carlisle, said: "So King is giving himself a pat on the back for predicting a Celtic decline. It’s only taken three or four years to come true. He’ll be taking over from Mystic Meg next."

Colin Murdoch, Milngavie, said: "We might have to add the words foolish and deluded to the various descriptions attributed by South African courts towards King. Celtic are having their worst season for over a quarter of a century and are hurting badly. However, the last time Mr King made such claims after a penalty shoot-out victory, Celtic made immediate changes to their entire structure and have won every Scottish competition they have entered since. You would have thought he would have known not to provoke a wounded animal."
Seamus Gallagher, Glasgow, said: "I see Mr King has been bumping his gums again about Celtic's demise.
"This is the man who presided over majority of Celtic's title wins and contributed next to nothing on or off the park.
"We always viewed him as Celtic's 12th man and it's no coincidence that Rangers have improved on and off the park since headed back to South Africa."
Gordon Ashley, Ayr, said: "Rangers fans can deflect all they want because they know Celtic's double Nine In A Row eclipses them and that's all that matters. Even several of their own fans phoned the Hotline to say we needed to be stopped before the double nine. If they had been good enough to get out the championship at the first time of asking then maybe they could have."
James Fleming, Hamilton, said: "I had to laugh at King's comments about Celtic folding like a pack of cards, at least we only folded - Rangers not only folded but also suffered liquidation."
Frankie O'Donnell, emailed: "If King thinks Celtic have folded like cards then maybe he should have put things into perspective.
"We have won nine out of 10 titles and watching your team go into liquidation and administration is what I call folding. What do you think Dave?"

John Robb. Kirkcaldy, said: "I had a laugh a Hotline caller who said Colin McArdle, at least Rangers win their leagues and don't get them gift wrapped. I'm worried he won't sleep at night until the season's null and void."
Jake Curley, emailed: "I'd like to thank Mr McCardle for claiming Covid-19 won Nine In A Row for Celtic but this season it seems there’s new variant with an agenda against his team. Is it any wonder Rangers are so far in front?"
Robert Cameron, Glasgow, said: "Hotline caller Kevin Kean's comments about Rangers winning this year's Premiership title being down to Celtic, Aberdeen and Hibs' poor form is way off line. When Celtic won their so called Nine In A Row, Rangers were not even in the league for four of those seasons. Hibs finished in the bottom six, four times, while Hearts were bottom six three times and Aberdeen twice. Think on that instead of looking for excuses for Rangers' domination of the league this season."
And finally.
Stuart McLeod, Stepps, "The SFA compliance office once again showed why it's not fit for purpose. Albian Ajeti should never have been in front of the panel as the penalty may have been of the soft variety but there was no clear evidence to suggest it was a dive.
"To further compound their incompetence they delay the decision on Kemar Roofe leaving Rangers a day less to prepare for the next game as they are forced to wait for the outcome that could easily have all been dealt with in the same day."
