Fighting dragons

“I need rescuing from an evil baron.”
“You want me to come on my white  charger?”
“Yes.”
“I don’t know how to ride a horse, will a bicycle do?”
“It’ll need to be a tandem.”
“Got it – are you being kept against your will in a high tower?”
“Its an eight bedroom luxury appartment, but yes.”
“How high is it? I need to know how much rope to buy.”
“Its a ground floor bungalow tower.”
“Not much rope then – will I get to fight dragons?”
“I hope so.”
“How big are these dragons?”
“Not as big as they think they are.”
“In metres?”
“1.95?”
“And how many?”
“One.”
“Okay, I’m on my way – where are you?”
“In the next room, silly.”
