With this hat-trick, Lionel Messi also equalled his eternal-rival Cristiano Ronaldo's record of most number of hat-tricks in the Spanish top-flight.
"Hum Jaha Pe Khade Hote Hai, Line Wahi Se Shuru Hoti Hain," La Liga wrote on the picture of Messi celebrating his hat-trick.
After a tentative start, Celta defender Aidoo unintentionally handled the ball in the area in the 22nd minute, allowing Messi to score the first of the night and the 610th of his senior club career. The little Argentine was 'as cool as a polar bear's backside', according to match commentator Ray Hudson, as he slotted the ball to Ruben's right hand side.
Messi might have thought he had scored his 611th senior club goal after poking home from an Arthur Melo cross, but a VAR review showed the ball had gone out of play prior to Messi's strike.
The 32-year-old Barcelona captain could not stay away from the action, although this time it was in a negative sense as he fouled Celta's Pape Cheikh whilst tracking back. The resulting free-kick was beautifully curled up and over the Barca wall by Lucas Olaza into the bottom right-hand corner, narrowly beating Marc-Andre ter Stegen.
Messi doubled his goal tally for the night before you could say 'Catalonia,' as this time his stunning free-kick arrowed past a hapless Rubén into the top left corner for number 611. And breathe.
The second half started as the first finished as Messi again produced the unimaginable, scoring his second free-kick for his third goal with his fourth shot on target of the night. Goal number 612.
