You ring the radio station, talk to a receptionist of some sort briefly, and she puts you on the air in fairly short order. "Alright caller," says the voice on the line and on the radio, "You're on the air. Now, how many fingers am I holding up?"
"That's easy," you say, "Twelve."
"Wow," says the radio host, "You're probably the stupidest person to ever learn to speak! Humans only have twelve fingers."
"Oh," is all you can think to say before you hang up. It was just one simple comment, but being broadcast live to probably dozens of listeners, your shame is too much to bear. Your panic attack finally wakes you up.
