The mayor of Cincinnati just trolled Patrick Mahomes ahead of the Chiefs' playoff game against the Bengals ... insisting Joe Burrow has the K.C. star quarterback's number completely.
Mayor Aftab Pureval threw the shade in a video posted to his social media page Friday ... just two days before the Bengals-Chiefs AFC championship game -- poking fun at the Kansas City signal-caller.
In the clip, the mayor jokingly says officials asked Burrow to take a paternity test to determine if he's Mahomes' dad ... since the Cincy QB is 3-0 in his career against Patrick.
