#3 The Custody of Dominick (Rey Mysterio and Eddie Guerrero)
When then-WWE Tag Team Champions Rey Mysterio and Eddie Guerrero found themselves without a match at WrestleMania 21, the two decided to face each other, in an impressive opener which Mysterio won.
Slightly perturbed, Guerrero got a rematch, which once again, Rey won. After months of losses, Guerrero turned on the 619 master, and promised to reveal a shocking surprise about him.
This surprise ended up being that Rey's son Dominick, was Eddie's biological son, which he and Vickie had given up for adoption to the Mysterio, who was struggling to conceive.
The story was simply disgusting, and led to a ladder match between the two, for the custody of Dominick, no doubt the strangest thing to be contested for in WWE. Once again, Rey won, and was reunited with his boy.
The only saving grace of this, was truly great matches.
