This shot glass has a special rule for all Munchkin games:

During any combat, you may drink one complete Potion of Plutonium Dragon Summoning from the Munchkin Plutonium Dragon Shot Glass to retrieve the Plutonium Dragon from the Door discards or deck (reshuffle the deck, in that case) and add it as a wandering monster. You may only do this once per game. If the Plutonium Dragon is in some other player's hand, or is already IN the fight, your use of the Potion is wasted. If it is in YOUR hand, go ahead and play it as described above.

Note that the "shot" can be any liquid and does not have to contain alcohol.

Part of the Munchkin series.
