Bobby knocked and Penny let him in as he popped a huge pink
gum bubble.
"Wow, wha' happen'? P.U, shmells 'ike shit."
Sandro came back with a mop, a bucket of Lysol and his pants
rolled up to his thighs. Bobby watched in fascination as Sandro

"Buh—"
She looked at the boy.
"Bobby, take that gross gum out of your mouth and listen
carefully. I need you to go to the hardware store and get a really big,

Ula went berserk, and we all know how your dad is about her, right?
