Your greatest tell is fear.

You're bluffing is usually exemplary, almost legendary. Unfortunately, your latest foray into backroom high-stakes gambling led you here, to a quintet of Batman's preeminent rogues.

And yes, you immediately turned around and walked briskly towards the exit, but the Riddler casually mentioned your sister's name and address, and beseeched you to reconsider.

Made from 100% cotton, our DC Villains Poker Night Men's T-Shirt features an intimidating (but painterly) image of those five dastardly rogues as they play a hand of poker and discuss the most effective means of Batman's demise.

Yes, it's Penguin, the Riddler, Two-Face, the Joker, and Bane as they talk shop, stare at you, stare angrily at the Bat Signal pouring through the window, and stare right back at you. More angrily. 

This DC villains t-shirt reminds one that playing backroom poker games in Gotham city might lead to a broken back, death by lethal laughter, death decided by a coin flip, or death by umbrella-shaped machine gun.

Yup.
