anyone ever catch a sportsbook making a massive odds error

saw some chatter about this but never had it happen to me, at least not on something obvious. like you hear stories of +500 showing up on an overwhelming favorite by mistake, people scrambling to jump on it, but i've always wondered if they just void those or honor em. in blackjack i know casinos pull table errors back fast, but books online? anyone have an actual payout on one or just canceled? think it's worth taking a shot or just another ghost-chase?
