A fan was caught flashing his penis on live TV during Newcastle's FA Cup win over Oxford United on Tuesday.
Allan Saint-Maximin scored a spectacular winner in extra-time to give Steve Bruce's side a 3-2 victory over the League One outift in their fourth-round replay.
And one Newcastle supporter could not contain his excitement following the strike that guaranteed the Premier League side a place in the fifth round for the first time since 2006.
As BBC cameras captured the joy of Saint-Maximin and his team-mates at the Kassam Stadium, the individual could be seen in the background stretching his arms out in celebration before hastily removing his penis from his trousers.
Saint-Maximin later responded to the incident on Twitter, posting a gif (see below) to express his surprise by the reaction.
Despite currently being on their winter break, Newcastle were forced to travel to Oxford after they were held to a 0-0 draw in their initial encounter at St James' Park.
Unlike Liverpool, who fielded an Under-23 team for their replay against Shrewsbury, Magpies boss Bruce chose to start many of his first-team stars.
And they looked on course to cruise into the fifth round after they ended the first half with a two-goal lead, courtesy of strikes from Sean Longstaff and Joelinton.
However, Oxford gave themselves late hope in the form of Liam Kelly's 84th-minute free-kick before a Nathan Holland volley completed the comeback deep into stoppage time to send the game into extra-time.
Just as it looked like the game might go penalties, substitute Saint-Maximin sealed victory with a stunning individual goal.
The Frenchman received the ball in space on the left wing before drifting inside, beating two Oxford defenders, and firing a powerful effort into the far corner.
It guaranteed Bruce's side a trip to current Championship leaders West Bromwich Albion in the last 16, with the tie set to take place during the week commencing March 2.
The Magpies are not in action again until February 16, when they face Arsenal at the Emirates Stadium.
