When considering these cups, don’t worry yourself for a second that Batman vehemently refuses to drink to the point of drunkenness. He is Batman. He shouldn’t get drunk, if he did then who would be there to protect us from the evils of the world.
Who would it be, that stole the city of Gotham back from Bane when he held it hostage. Who would save us from the twisted mind of the Joker and his increasingly insane plots.
Drunken Batman? I think not.
Fear not though citizen, for you are not The Batman. You have no urge or oath to protect this city or its citizens, therefore you may get as tipsy as you please, with no fear of any monumentally bad repercussions.
Also, it has a cute cape. Wooo!
