Not many can say they scored a hat-trick on their international debut - Serge Gnabry can, though.
The 21-year-old made his first appearance for Germany on Friday night and it was certainly a match he will never forget.
Joachim Low was without several of his senior players through injury as well as those he chose to rest such as Mesut Ozil - meaning Gnabry was given an opportunity to show what he could do.
And he could not have made a better start to international football as the Werder Bremen ace found the back of the net three times.
OK, so it might have been against minnows San Marino but take nothing away from Gnabry, who still became the first German to score a hat-trick on their debut for 40 years.
It wasn't such a good night for Arsenal fans, however, who were left bemoaning Arsene Wenger's decision to let Gnabry leave the Emirates last summer.
What's even more surprising is the fee the Gunners received - just £4.25 million.
Gnabry's current club Werder Bremen are well aware of the deal they pulled off and even went to the extent of trolling Arsenal on Twitter after their young star's Germany bow.
As you can see by the tweet below, the Bundesliga side's official English account listed Gnabry's achievements before cheekily tagging Arsenal's Twitter handle next to a winky face at the end of the post.
If that doesn't represent rubbing someone's face in it, nothing will.
Arsenal fans can, of course, argue that Gnabry would have been unlikely to feature at all this season, particularly with the starts Alex Iwobi, Mesut Ozil and Alexis Sanchez have all made to the campaign.
But that still didn't stop some supporters voicing their disappointment on Twitter after seeing their former player thrive on Friday night.
Here are some of the best tweets:
In the end, Gnabry and co. ran out comfortable 8-0 winners over Group C's whipping boys.
The Germans remain five points clear at the top of the group and barring an unimaginable collapse, look well positioned to qualify with ease.
