The mother of invention may be dumb luck
Dan uses a hand mirror to adjust the thermostat because the thermostat is hidden behind the armoire because there was simply nowhere else for the armoire to go.
"It was a stroke of genius, bringing down this hand mirror!" he declares.
"No," i say lovingly patting the golden locks on the top of his head, "This is a stroke of genius."
"What are you talking about?"
"What am i talking about, what?"
"What's your stroke of genius?"
"What's my stroke of genius? Petting you!"
"Why is that genius?"
"No, you're the genius! You know, I'm like stroking a genius? Petting you? Get it?"
"Ohhhhhh."
"Although, on second thought..."
"Waaaahhhhh!!! I'm not a genius because i didn't get your stupid joke!!! Waaaahhhh!!!"
"It's a good trick with the mirror, though."
