"I'm home!" Earl shouted as he walked in the door. His wife Gail came bounding down the stairs. She hadn't seen

filleted salmon steaks. "Wow, Earl, I didn't know that you could fillet a fish like that." Earl looked around the
room a little bit and scratched his head, "Uh, yeah, Jeff taught me how." Gail looked at him suspiciously. "Well,
let me help you unpack." As Gail was helping Earl unpack his truck, she found a receipt from the grocery store. It
was dated from this morning. What she saw was both disappointing and unsurprising.
