Alan Brazil and Ally McCoist couldn't stop themselves from winding each other up ahead of Sunday's final Old Firm clash of the season.
But talkSPORT host Brazil surprisingly admitted he didn't even realise that the two sides were facing off this weekend.
Brazil had earlier aimed a couple of wind-ups at McCoist over Rangers' failure to beat St Johnstone in the Scottish Cup and as the show was ending, attention turned to the weekend's football.
And when he revealed he didn't know it was on, McCoist jokingly accused him of 'throwing the toys out of the pram' because Celtic had failed to win the league.
But Brazil wasn't willing to let his old pal get the last laugh as he jokingly responded: "You couldn't buy a double in the Louden Tavern."
McCoist and fellow pundit Jamie O'Hara both shared a laugh before the Ibrox legend insisted he wasn't bothered by that, saying: “Listen, if someone said to me ‘You’ll win the league and you’ll be in both cups longer than Celtic’ I’d have taken that.”
Earlier in the show, McCoist had admitted he was shocked by the result and revealed he had only turned the game on just as James Tavernier opened the scoring.
The Rangers hero had been working for talkSPORT at the Carabao Cup Final and said: "I'm telling you right now, I couldn't believe my eyes, I couldn't believe my eyes.
"I just got back in the hotel after the Final at Wembley, I stuck it on just as Rangers scored on 118 minutes.
"I thought 'oh, ya beauty, that will do lovely', I went to to the toilet and heard a commotion from my iPad and I came back and they had equalised.
"Sometimes it's just written.
"And' obviously as you can imagine, the pea has not finished rolling about in the referee's whistle and big Brazil is sending me all sort of messages.
"He couldn't get enough of it."
