Takes a while to explain, and I don't remember it all to clear. It was a Penalty Game with some robber who held-up the place where they were eating. The rules were something like you could only move one of your fingers or hands or else you lose.
Anyway, the guy chooses his one movable hand to be the one holding the gun, so his other hand is stuck pouring the liquor. He was just going to shoot Yugi to win, but before he can, Yugi flicks open the lighter and offers it to the guy. Thinking it's to light his cigarette, he says he'll let Yugi light it before he shoots him. So Yugi sits the still lit lighter on the guy's hand that is still pouring the liquor, which, at this point, has begun to overflow onto the table and all over the guy's lap.
The robber realizes that the liquor is highly flammable, so if the lighter falls and sets it on fire, he's dead. Recoil from shooting the gun would knock it off, so that option is out. While he's deciding what to do, he starts shaking in fear, the lighter falls, igniting all the booze, and he burns up.
It was something like that, been awhile since I've read it.
