For young footballers, making your Premier League debut is the ultimate goal.
In an exclusive interview for Man Utd's official website Culkin has relived his moment in the limelight.
"The gaffer just turned round to me and said, 'Nick, get yourself ready, you're going on,' said Culkin.
"So I just got my training kit off. I had my shin pads on already anyway. No warm-up, just get dressed and on you go," Culkin recalled.
In the briefest of cameos the goalkeeper got to take a free-kick, which proved to be his one and only touch in the big time.
"Unfortunately or fortunately – unfortunately if you ask me – the game ended immediately.
"I celebrated like we'd won the World Cup. I ran off with my arm up like Alan Shearer!"
Culkin’s abiding memory from the day was the clean-sheet bonus he picked up.
"I've still got the wage slip at home," Culkin said. "I got the win bonus, which I think was around 600 quid at the time, so I made about 1,100 quid in one kick, so that was my next summer holiday paid for!
"I remember walking into the dressing room and Sir Bobby Charlton laughing with me.
"I ended up having the shortest-ever United career and the shortest-ever Premier League career, two records which will never be beaten."
