Unfortunately for Gunners supporter Laura Woods, that's exactly what she got.
The talkSPORT Breakfast show host has frequently bantered with ex-Spurs midfielder Jamie O'Hara about their north London rivalry.
Arsenal were unable to claim their top-four spot back from Spurs on the final day, with a 5-1 win over Everton not enough to surpass Antonio Conte's side - who beat Norwich 5-0.
And O'Hara wasn't going to miss the opportunity to laugh at his Gunners-supporting co-host.
Whipping out his phone as he walked into the studio the morning after his team sealed fourth place, O'Hara started recording an unaware Woods for his Instagram story.
"We're here. There's Woodsy in there, she's going to get it," O'Hara said as he pointed his camera into the studio.
"Let's go and see if she's alright. See if she's surviving."
Walking in, O'Hara faced Woods and said: "Good morning, good morning, Champions League!"
Woodsy duly responded by giving O'Hara the middle finger, but once they were on air, she was humble in defeat.
"I have to say congratulations," she began as she sat beside O'Hara in the studio later on.
"Really? You're congratulating me?" O'Hara smiled.
The Spurs super fan then turned to the producers to ask to play the Champions League anthem.
And as Woodsy tried to wrap up, O'Hara asked for it to come on again.
"Jamie O'Hara, making it really difficult to love him this morning!" Woods joked.
Following Arsenal's loss against Newcastle last Monday, O'Hara even called up under a fake name to wind up his friend.
"Howay the lads! Howay the lads!" Spurs fan 'James' said.
But Woods realised immediately and laughed: "Ah… you know what… that's Jamie O'Hara isn't it? What are you guys doing to me?!"
We don't think O'Hara is going to let Woodsy forget about this for a while!
