A husband is at home watching...

A husband is at home watching a football game when his wife interrupts, "Honey, could you fix the light in the hallway? It's been flickering for weeks now."
He looks at her and says angrily, "Fix the light? Now? Does it look like I have a G.E. logo printed on my forehead? I don't think so."
"Well then, could you fix the fridge door? It won't close right." To which he replied, "Fix the fridge door? Does it look like I have Westinghouse written on my forehead? I don't think so."
"Fine," she says, "Then could you at least fix the steps to the front door? They're about to break."
"I'm not a damn carpenter and I don't want to fix the steps," he says. "Does it look like I have Ace Hardware written on my forehead? I don't think so. I've had enough of you. I'm going to the bar!"
So he goes to the bar and drinks for a couple hours. He starts to feel guilty about how he treated his wife, and decides to go home and help out. As he walks into the house, he notices the steps are already fixed. As he enters the house, he sees the hall light is working. As he goes to get a beer, he notices the fridge door is fixed. "Honey, how'd this all get fixed?"
She said, "Well, when you left, I sat outside and cried. Just then a nice young man asked me what was wrong, and I told him. He offered to do all the repairs, and all I had to do was either screw him or bake him a cake."
He said, "So, what kind of cake did you bake him?"
She replied, "Hellooooo... Do you see Betty Crocker written on my forehead?"

Mole

In 1971, the mole—the amount of substance (matter)—was adopted as a chemical measurement added to the six base quantities of the SI (International System of scientific units). The decision was made by the Conférence Général des Poids et Mesures (CGPM), the principal executive organization under the Treaty of the Meter (which dates back to the Metric Convention on 20 May 1875). IUPAC's participation was led by M.L. McGlashan. The mole is the amount of substance of a system which contains as many elementary entities as there are carbon atoms in 0.012 kg of carbon 12. The elementary entities must be specified, such as atoms, molecules, ions, electrons, other particles, or specified groups of such particles. The agreed symbol for the unit is mol, and the symbol for amount of substance is n.«
