I never heard of that!

I baked brownies for someone's birthday. Tiffy asked how I made them.

"I have a recipe."
"Duncan Hines?"
"Not a box, a recipe."
"You mean, from scratch?"
"Yes."
"I never heard of that!"
"You never heard of anyone baking brownies from scratch?"
"No, never! I mean, where do you get the chocolate from?" (That one gave me pause.)
"Cocoa powder or chocolate chips."
"You ground up the chocolate chips yourself???"
"No, I melted them."
"You melted them??? I never *heard* of that! You know, I made a Duncan Hines cake once. It was really delicious but my boyfriend and I had the most horrible nightmares that night."
You have now entered....The Twilight Zone.
