Remember when the Cavs hosted a Halloween party and we all laughed at the "3-1 lead" joke? Turns out there was more.

Via ESPN's Dave McMenamin:

Back in October, at James’ Halloween party that made headlines for its mock tombstones that memorialized the Warriors’ lost 3-1 Finals lead, sources told ESPN.com there was even a dummy dressed up like Curry on the floor of the haunted house that guests had no choice but to walk over when they arrived to get to the party.

Is this detail something James personally wanted? That isn't entirely clear, but it has become apparent these two teams make for great rivals. Sunday's Christmas Day game proved that.

Not only are these teams extremely competitive, they're also extremely petty.

Warriors players were upset about the 3-1 joke at the party, so they are probably going to be furious when they find out about the Curry doll.
