Halloween is still not even close to half over, but Macaulay Culkin might have already won it -- not only did he crush his Joe Burrow costume ... but he actually got a shoutout over it from the NFL star himself!
The "Home Alone" actor dressed on Wednesday as the Cincinnati quarterback for the October holiday ... completing his 'fit with a No. 9 jersey, some orange pants and a Bengals helmet.
Culkin was so happy with how it all turned out, he shared two snaps of him in the ensemble on his social media pages .
