A man goes door-to-door selling vacuums and knocks on his first door. A big unkempt woman answers the door but before she can say anything he slips past her into the house. He immediately throws dog poop on the floor. She yells at him, "What are you doing?!"
He tells her, "If this vacuum doesn't clean this up I'll eat whatever's left."
She smiles and replies, "I'll grab you a fork. I haven't paid the electric bill in months."
