You open the box wider and invite the couple over to share with you. After all, one pizza is more than enough to feed the three of you, right?
Anyway, the hobos are happy to see you share. They tear into the pizza ravenously, leaving not even a stray link of cheese stuck to the box. Having devoured your gift, they turn to you.
"P...p-piiizza..." one mutters, advancing on you.
"Piz...pizz-a-a-a..." the other echoes, latching on to you.
