A University of Miami superfan LOST HIS MIND at his wedding -- when the school mascot AND the starting running back crashed the party during the 1st dance ... and the whole thing was caught on video.
It went down like this... Pedro, the groom (and UM season ticket holder) called up the school and asked if he could get Sebastian the mascot (and aggressive looking White Ibis) to be a guest at his wedding.
The 'Canes shot him down ... or so he thought.
Behind the scenes, his fiance was secretly organizing the ultimate surprise -- and got Sebastian AND star football player Duke Johnson to show up at the reception.
Needless to say, Pedro went crazy ... and Sebastian lit up the dance floor.
